I think it isa definitive piece of writing and lays out the issues of publishing in theface of changing technology quite well.  Important reading for all concerned.(One side note - the document was formatted for viewing with a Web browser.I've cleaned up things to the point of keeping lines at 80 columns or less.)------November 30, 1994I am pleased to enclose a copy of the ACM's electronic publishing plan, whichcontains our vision about the future of scientific publishing and our program toachieve it. Our interim answers to the policy questions raised in this plan arerecorded in two separate documents, the ACM Copyright Policy and ACM Author'sGuide to the Copyright Policy, which are also being distributed to you. Thesedocuments are available on <acm.org>.I hope you will read this plan carefully. With all the changes in digital mediaand publication, there is much going on that deserves your reflection. If youhave comments, please send them to Mark Mandelbaum, Director of Publications, atACM (Mandelbaum@acm.org).Cordially,Peter J.

DenningChair, Publications BoardBernard RousDeputy Director, ACM Publications11/30/94IntroductionPublishing has reached an historic divide. Ubiquitous networks, storage servers,printers, and document and graphics software are transforming the world from onein which only a few publishing houses print and disseminate works, to one inwhich any individual can print or offer for dissemination any work at low costand in short order. This poses major challenges for publishers of scientificworks and for the standard practices of scientific peer review.The ACM aims to be one of the first scientific society publishers to cross thedivide. ACM has embarked on an ambitious electronic publication plan. The planand the reasons for adopting it are set forth below.The Association for Computing Machinery is the first scientific and educationalsociety formed in the computing field (founded 1947). From the very beginning itentered scientific publishing by establishing the monthly Communications of ACMand a peer review process for accepting papers into it. Over the years, itslibrary of traditional journal-type publications has grown to the present sizeof 17 periodicals including the one monthly, several bimonthly, and the restquarterly. Its 78,000 members hold 55,000 subscriptions to its journals andnonmembers hold another 12,000 subscriptions. In the 1960s, ACM established aseries of special interest groups (SIGs) that started issuing informalnewsletters of their own and began to hold conferences and symposia thatpublished proceedings. Over time, this grew into a large enterprise, featuring90,000 memberships in 39 SIGs that sponsor 45 conferences per year and print17,000 pages of proceedings. All told, ACM literature is growing at the rate ofapproximately 1 gigabyte per year. The publications of the traditional journalsand SIGs constitute a large enterprise, on the order of a third of ACM's$30-million budget.The Scientific Publishing TraditionThe scientific publishing tradition is a collection of practices and assumptionsthat have become part of the values and common sense of science. A central tenetof this tradition is publication only after careful and deliberative review byexperts. Not only is it considered wasteful to publish a paper that containserrors or repeats earlier work, it is an affront to the tradition of science topublish statements easily refuted by experts. Another tenet is that everypublished paper is a permanent member of the library of all scientificliterature. Many of the scientific societies established their own publishinghouses and established review processes; through their membership, they haveaccess to the expert reviewers and they have a ready-made audience of readers.The societies ensure that repositories exist containing back issues of theirpublications.In this tradition, a journal paper passes through four phases, separated bythree key moments of public declaration:A. Preparation -- author drafts preliminary version with early results andobtains informal review by close colleagues. This phase ends with the submissionof manuscript to an editor with a request to review and publish it.B. Review and revision -- editor commissions reviews from several experts,called "referees", and, based on their advice, either rejects or requestsrevisions from the author. This phase ends with the editor accepting the paper.C. Publication processing -- editor sends manuscript to publication office forcopyediting, layout, queueing, and printing. This phase ends with the actualpublication of the paper in a journal and its dissemination to subscribers.D. Archiving and indexing -- societies and libraries preserve back issues;libraries catalog papers; abstracting services summarize recent papers; citationservices accumulate citation indices. Students and other readers use theseservices to locate works long after they were published.The second and third phases typically take 6-18 months each, or a total timefrom submission to publication of 12-36 months. The fourth phase is ongoing.The phases are separated by three key public declarations:1. Submission -- author declares the paper submitted to an editor; this isdocumented by a letter to the editor.2. Acceptance -- editor declares the paper accepted; this is documented by aletter to the author.3. Publication -- publishing house prints and distributes the copies of thejournal issue in which the paper appears.A copyright transfer usually takes place as part of acceptance. The authorgrants the publisher the right to use the work in any form for any educationalor scientific purpose of the publisher's parent scientific society and retainsrights for patents and reuse of the work.The system relies heavily on the will of the society to continue the journals bymarketing and managing subscriptions, setting standards, and appointing neweditors. This system also relies heavily on the volunteer efforts of experts andeditors. Most of the editorships are volunteer positions; most societies formsearch committees to locate new editors-in-chief and delegate to theeditor-in-chief the authority to appoint associate editors. The reviewers arealmost always volunteers; it is the common sense of the field that an author whosubmits a paper "owes the field" three reviews. In practice, many reviewersreport that they receive an average of one manuscript a month for review andthat it takes them 2 to 6 months to complete a given review.Most publishers follow three additional policies. One is a "novel submission"policy, under which an author is expected to submit substantially new materialthat does not overlap significantly with previous submissions by that or anyother author. Second is a "no scooping" policy, under which an author has noauthority to distribute copies publicly until the paper has actually beenprinted. Third is a "proper citations" policy, under which an author is expectedto give proper credit to all other persons who contributed to the work in someway, either through previous publication or through private communications.Authors who violate these policies typically receive reprimands from editors andmay jeopardize their future right to publish with those journals.These policies and practices collectively serve to provide an "imprint" orimprimatur to the novelty and soundness of published scientific works. Thesociety gains prestige in the science community by seeking to publish only themost novel, significant, readable, and well-grounded works. The authors gainprestige in the science community by having their works published in prestigiousjournals. The imprints of a society can be of significant professional value toan author -- for example, academic authors consider them essential to promotionand tenure. The harder it is to achieve the imprint and the higher the qualityit signifies, the greater its value to an author.Although less visible, the policies and practices of archiving and indexing areas critical as publishing. A society's imprint would be worthless withoutreasonable assurances that the published work will be preserved for posterityand that readers can locate the work without having to locate the author.Authors who argue that the publishing process ends with publication areforgetting the importance of archiving to the preservation of their work.Breakdowns in the Traditional SystemThe traditional scientific publishing system is now facing a variety ofbreakdowns that must be overcome if the system is to survive. We assume thatresolving these breakdowns is preferable to abandoning scientific publishing.>From ACM's perspective, the breakdowns are:1. Most of our journals are written by experts for otherexperts, but these experts constitute less than 20% of the readership. The other80%, who are typically experts from other subdisciplines or are practitioners,may be interested in the results but do not have the time or background tounderstand the specialized language of the journal's domain experts. These 80%are showing their growing dissatisfaction with the enterprise by complainingabout too many esoteric papers, dropping their subscriptions and sometimes theirmemberships, and demanding new kinds of publications that they find moreapproachable. With the increasing penetration of computers into everydaypractices of society, this group is growing. In ACM we refer to the traditionalline of publications, which are the majority of our journals, as "Track 1". Weare gradually introducing a new line of publications aimed at the other readers;we call these the "Track 2" publications. Among other things, the Track 2publications can bridge between practitioners and research scholars.2. Authors are increasingly dissatisfied with delays in theprocess. It often takes 6-18 months to complete the review-revise phase, andanother 12-18 months after that until actual publication. Even if we couldmagically remove the publication delay by clever use of advanced technology,authors would still be dissatisfied with the long review time. Moreover, readersare dissatisfied if they believe that a result known 1-3 years ago has takenthis long to be published.3. It is an increasingly popular practice among authors to posttheir manuscripts on publicly-accessible FTP servers at or before the moment ofsubmission, thus making the moment of publication precede the moment ofacceptance. This practice, sometimes called "circulating preprints", not onlyaccelerates the dissemination of new results, it is seen by many as improvingthe quality of works by subjecting them to wider scrutiny than that of a fewreferees. This obviously poses a challenge to the policy of not consideringpreviously published works.4. New questions are arising about who owns (or should own) thecopyrights. Since the FTP server is becoming the author's means of dissemination(at least to a core group of interested persons), some authors now wonderwhether there is any value in signing over the right to disseminate to apublisher -- and some openly wonder if there is any need for the publisher atall. Other authors are looking to publishers to be their agents in bringingtheir work to the widest audience, and protecting and preserving their work.Artists, following their standard practice, often retain copyright to their artimages, and only give permission to include those images in specific papers;this challenges the policy that the publisher may freely distribute copies ofthe entire paper and complicates electronic redistribution.5. Libraries are suffering under reductions of theirbudgets at a time when subscription prices have been rising faster thaninflation and the number of scientific journals has been growing rapidly. Theyare dropping journal subscriptions and joining together in consortia that shareone subscription among several institutions. They do not save all publishedjournals; they look instead to the professional societies to do that. Thisthreatens the archiving function by removing the commitment to retain all worksindefinitely.  It is highly likely that many scientific works exist ascitations only (the original documents have been lost), and that many othershave been lost completely.6. The relentless rise of the number of printed journal papersand their prices, and in the number of manuscripts distributed by electronicmeans, is causing "information overload". Individuals and institutions alike areshifting from a mode of acquiring publications for "just-in-case" use to a modeof acquiring them "just-in-time". The latter mode is increasingly facilitated byon-line reference databases and document delivery services. This trend, whichappears irreversible, will eventually lead to the disintegration of printjournals as pre-selected collections of worthy papers.7. Although publishers say that it is not in their mission tocater to academic concerns for recognition, tenure, and promotion, theseconcerns nonetheless have been a powerful engine in the scientific publishingindustry.  Authors tend to submit to journals with the highest perceivedprestige. Tenure committees are beginning to assess the value of the imprintrather than the print journal itself. Submissions to traditional journalscontinue to INCREASE even as readership decreases, leading to what some arestarting to call "write-only journals".8. Authors are increasingly viewing their works as "living in theweb", an allusion to the rapidly growing World Wide Web of interconnecteddocuments. They see networks as new opportunities for collaborative authoringand for "dynamic documents" that incorporate other documents by link ratherthan by direct copying. Over time, authors want to introduce either newversions or changes into their own works. This is raising new problems ofversion control, copy-on-demand when exercising a link, reference, citation,and copyright of a non-fixed work.9. Authors of works stored in the "web" increasingly use activehypertext links to other works rather than the traditional citation. "Clicking"on the link invokes a process that copies the referenced work from a remotesite.  Such a link, when used, becomes a way of incorporating another work ondemand into a document. Link-use is not contemplated in existing copyrightpolicy.10. Some authors are posting complete collections of theirpersonal works on servers where others can locate them easily simply by knowingthe author's name.In effect, the three key moments of the traditional process -- submission,acceptance, and publication -- are no longer distinct or in traditional order.The moment of publication is, with the help of public servers, increasinglylikely to precede the moment of submission. The moment of acceptance is becomingthe moment of imprimatur. Printed publication is becoming less important toauthors. The responsibility for archiving and indexing is gradually beingabandoned by librarians, who cannot afford comprehensive collections or thesoftware tools for electronic archives.ACM's Response as a Society PublisherThese breakdowns, and the other changes in means of publication anddistribution, show that the scientific publishing enterprise is beingtransformed. The broad outlines of what will emerge are already discernible inthe practices of some publishers and in the visions many are expressing of thefuture. These outlines are centered around a structured database containing thesociety's published works.o Journals will become "streams" flowing into the society'sdatabase and will retain their identities as "database categories"; at themoment of acceptance, a paper will be placed in the database rather than intoa print queue at the publication house. Separate issues and page limits willdisappear.o Societies will offer facilities and mechanisms wherebyauthors can post collections of their works and obtain public comment on earlyversions of them.o Individuals will cease to purchase journal subscriptions andwill instead purchase a right of access to the entire database. They will postinterest-profiles and will be automatically notified when new items matchingtheir profiles are posted. They will read from the database and will beresponsible for their own printing. The publisher may provide print copies ondemand or by fax for a fee.o Publishers will distribute "notices of availability" rather thanjournals or documents; readers will locate and obtain copies on demand using newsoftware tools. Local agents specializing in print-on-demand will be establishedin print shops, copy shops, and libraries, especially at universities.o New kinds of services such as search, extract, and repackaging will be madeavailable.o New kinds of works including hypertext, picture, graphics,sound, and other multimedia effects will be sought andaccommodated. New paradigms of works such as trainingpackages will also beaccommodated.o All interactions between author and editor, and betweeneditor and reviewer, will be conducted by networked services. This will includeall coordination concerning reviews and revisions.o The publishers will cooperate in "virtual libraries", offeringcombined access to library patrons. Thus a member of ACM may also have access toworks stored by IEEE.o Advertising services will become more attuned to individualinterests and concerns. Links will be established between literature and relatedproducts.o The society's database will also contain non-archivalitems such as calendars of events, conference schedules, employementopportunities, and industry news.o Access to the society's database and its basic serviceswill be the core of the membership package.These transformations have already begun. The clock cannot be turned back. ACMauthors are already placing documents in databases in the world wide "web" ofinformation servers. ACM has developed enough of a conceptual framework toposition itself boldly in the new world whose general outlines are describedabove. ACM is undertaking to reinvent itself as a publisher.In response to the shifting digital media and networks, and to the breakdownsenumerated above, the ACM has embarked on a four-part strategy:1. Move aggressively toward having the entire ACMliterature in an on-line digital library. The service should be capable ofsupporting capture and production of works should be available by second quarter1995 and general dissemination within a year thereafter.2. Ameliorate the problems of Track 1 transactions by variousdelay-reducing improvements. Eliminate processing delay by publishing in thedigital library. Be prepared to phase out print versions and phase in electronicdistributions.3. Establish a new line of publication offerings ("Track 2") forthose devoted to using and applying technology, those who seek more generalinformation about current technical developments, and those who seek tounderstand current research.4. Engage in many experiments with new forms of publishingand publication services. Add the best of these to the repertoire of digitallibrary services. Revise copyright policies to encourage and accommodate thechanges fostered by these experiments.These strategies are described briefly in the four sections following.Although it is not part of the Publications Plan, the ACM has also made it a toppriority to encourage and develop an ACM electronic community, supported by avariety of networked services administered through the Internet host acm.org.All the individuals who volunteer services to the profession through ACM are nowusing the email and bulletin board facilities of Internet to coordinate theiractions. Members who do not have Internet accounts can purchase one from ACM ata nominal monthly fee ($12). The new ACM publication structures will exploit theACM networked services heavily.ACM Digital LibraryThe core technology of the ACM approach is a database that serves as an on-linelibrary of ACM's entire literature and offers a range of useful services forelectronic publication. It is being developed in two phases. Phase 1 is aninitial database and tools to use it for production of publications; thisdatabase will come on line and begin accumulating contents in spring 1995. Atthat time, all new submissions will be in digital form and the system willsupport capturing, storing, and linking certain non-textual objects such aspictures, graphs, equations, sound, or movies. Documents will be stored inseveral formats, including SGML, that will permit all their component objects tobe recognized during searches. Phase 2 is the deployment of distribution andaccess services; it includes establishing a network of servers of ACM materials,installing authentication and payment services, developing search and retrievalservices, and interfacing with "intelligent agent" services. In populating thedatabase of Phase 2, ACM plans that works published after 1994 will be stored infull digital format (original and SGML files, and possibly PostScript files).Works published before that will be captured whenever possible in digitalformat, and most works before 1990 will only be available as text images. Thedatabase and distribution services are being designed around these assumptions:o Electronic documents whose contents are logically structuredfor search and retrieval will be preferred to electronic analogs of the printedpage.o Visualization of scientific data through multi-mediapresentations will supplement and enhance text-only documents.o Documents will be object-oriented, with some components beingother objects already published in the worldwide web.o Not all documents will be read-only; some will be interactive.o Documents will be sought as needed by readers; hence easyaccess, high availability, and good performance are essential.o Access from home, work, or school desktops from around theworld will become a primary mode of acquiring knowledge. Good network access isessential.o Tools to help avoid information overload will acquire centralprominence. These will include personal information agents to assist users inselection, filtering, and interpretation. They will include standard interfacesto distributed collections of scientific information from many societies, andwill replace the current eclectic set of Internet tools and protocols. Societieswill continue to serve domain and discipline needs.We have made it a high priority to develop authentication services, which willbe needed to control access to the database and its functions. We willimplement new functions, notably access licenses for institutions, short termlicenses for non-members, promotional licenses, and triggered functions such as"intelligent agents" that collect copyright release fees from nonmembersaccessing ACM copyright works.Track 1 PublicationsOur short-term objectives are that all print journals and transactions bepublished on their schedules; that some be expanded from quarterly to bimonthlypublication when the backlog and subscribership would support the increasedcapacity; that joint journals in overlapping interest areas be established withother societies, for example, the Transactions on Networks with IEEE; thatspecialized journals of other publications be offered at good prices to ourmembers, for example, the Multimedia Systems journal of Springer-Verlag.Our long-term objective is to transition all our journals to on-linedistribution. A number of benefits arise from this: articles are availablesooner, costs of printing and binding can be shifted to local sites where theybecome optional, postage and warehousing costs can be eliminated, individualscan gain access to articles without subscribing to a whole journal, andpreliminary versions of papers can be posted for public comment. Print versionswill be phased out as the demand for them becomes too small, an outcome thatmay happen for some journals as early as 1998. We do not expect that printversions of Track 1 publications will be a major source of revenue for ACM inthe long term.We are also undertaking experiments in electronic distribution. In 1995, a newon-line electronic journal of combinatorial and numerical algorithms will beginoperation; it will include the current CALGO. Subscribers to TODS will beoffered on-line access to the queue of TODS papers that have not yet beenpublished.  Subscribers to TOPLAS will be offered on-line access to appendicesof published papers, which can then be printed in a shorter form. Patrons ofSupercomputing 94 will get the proceedings on CD-ROM. Other conferenceproceedings such as SIGGRAPH and SIGDA may be distributed on CD-ROM in 1995.Track 2 PublicationsMany ACM members have expressed concerns for learning and effectively using thebest new results of technology. ACM has responded to these concerns byrepositioning the Communications, by undertaking a new line of "Track 2"publications, and by cooperating with some commercial publishers on offeringsfor our members' "Track 2" interests. ACM started two new "Track 2"publications in 1994: StandardView, a magazine devoted to the debates andcontroversies in the field of standards, and Interactions, a magazine devotedto the practice and art of software design. We expect print versions of Track 2publications, including those on CD-ROM, to be a viable business: not only isthe market for them wider, but their preparation tends to be sufficientlyexpensive and time-consuming that most authors will seek professional help andfor their production and will expect income from their use.Track 2 is not just a type of publication, it is a way of thinking aboutengaging researchers, developers, and practitioners together in the ongoingprofessional learning process. It is a new way of generating offers formembers. Other parts of ACM, such as SIGs and education, are also consideringnew, "Track 2" programs.ExperimentsExperimentation with new practices is the only way to find out which ones willbe effective. Accordingly, we encourage experiments in electronic publicationand seek to facilitate them with new copyright policies. Here is a partial listof the experiments that are underway or will be undertaken soon:o on line journal of algorithms (including combinatorics and CALGO) o subscriberaccess to backlog queue of TODS o publishing TOPLAS appendices on line, therebyshortening print papers o on-line payment and authentication systems o local(e.g., campus) distribution in return for digitizing past literature o SIGconference proceedings on CD-ROM or server o back issues of journals on CD-ROMo Participation in Stanford NSF digital libraries project o Participation inJournal of Universal Computer Science (JUCS),a multinational publication venture in the World Wide Web o Cooperation with MITPress in distributing ChicagoJournal of Theoretical Computer Scienceo metering use to charge for copyright release o local agents (e.g., libraries)for search and print-on-demandNew ServicesThe structured database described above positions ACM to offer new services thatwill make ACM members differentially more competitive than nonmembers. Overtime, ACM expects to realize less revenue from print media and Track 1publications and more from three new principal businesses:1. Guided Access to Literature. Members will be given access to the ACM digitallibrary (and to similar services of cooperating societies) from which they cansearch and extract documents or summaries. They will be notified of new itemsthat match their interest profiles. Nonmembers can purchase short-term licenses.2. Conferences. Conferences will continue to expand. Some of them will beconducted in the Internet. Proceedings will be rapidly available either bynetwork or by CD-ROM.3. Continuing Education. ACM will offer reading and discussion programs based oncollections from the database. Those who pass the quizzes designed with theseprograms will receive certificates of knowledgeability issued by ACM.Servers and LinksIt is becoming a standard practice among engineers and scientists to post copiesof their papers on servers attached to the Internet and maintained by theiremployers. These papers can then be accessed from other servers in the Internetand copied by some form of file transfer protocol (FTP). Readers can attachcomments to the posted versions, and authors can post revised copies. Someeditors have established moderated "preprint comment services" to assist authorsand to guarantee that no papers or comments can be modified once posted. Thesepractices are widely seen among authors as means to speed the distribution offindings and to improve the quality of papers and algorithms.A growing number of professional authors and researchers are posting completelibraries of their personal works on servers; they seek protocols whereby theserver holding the complete works of any author can easily be located. This isseen by many authors as a way of establishing a "network identity" and makingtheir works more readily available to anyone who wants them.It is also becoming a strandard practice to think of papers as collections ofobjects (sections, paragraphs, figures, tables, pictures, and the like) ratherthan simply as texts. The world wide web (WWW) offers the technology of links,allowing authors to embed pointers to, rather than copies of, objects in theirworks; the reader can "click" on a link and thereby invoke a process that callsa copy of the object to the local computer. The new practice of links-use iswidely seen by authors as a means to constructing multimedia, nonlineardocuments that incorporate by reference relevant works from anywhere in theworld. It is also seen as a way to simplify construction of new works that relyon other works: the author of a work does not have to obtain prior permissionto include another work since the other work is not actually incorporated atthe time of writing. In other words, the link is seen as a citation and a copyof the work is obtained upon an explicit request by the reader.These new practices are bringing authors and readers into conflict overcopyright laws. Authors maintain that links are citations and it is theresponsibility of the copyright owner to demand permission when a reader usesthe link. Copyright holders maintain that the author is in reality intending tomake a copy available to the reader and must obtain prior permission.Copyright holders are beginning to design authentication servers so thatcertain people (such as members of a professional society) can get access aspart of their dues while others must pay to gain access; the holder may offerthe prospective reader a free preview to help that reader decide whether afull copy is worth paying for.ACM has decided to treat links as citations. ACM encourages wide use of links ascitations. Authors will not have to seek prior permission to place links to ACMcopyright works in their new documents. A reader who decides to use a link willnegotiate access with ACM at the time of link-use, and ACM will providemechanisms to make this simple. ACM members and authors will not be subjectcopyright release fees when fetching from the ACM databases.The scientific publishers, such as ACM, are examining ways to structure theircopyright policies so that they can preserve the spirit of the existingcopyright laws within the context of new practices for using servers and links.Until people have settled into standard routines with the new practices,authors and readers will have to think carefully about the copyrightimplications of their actions.Policy QuestionsThe experiments and new media are shifting traditional practices, demanding newpolicies to cover all aspects of the transformed publications processes. Theforegoing discussion reveals a number of policy questions that were notcontemplated when the existing policies were formulated.1. Who holds what rights? Do traditional copyright principlesapply to digital versions and transmissions? What rights do authors retain?Their employers?2. What rights do authors and ACM obtain for object-orienteddocuments, some of whose components are already-existing, published objectsreferenced by active hypertext links in the web? What happens when an authorobtains permission, but not copyright, for an object belonging to anotherauthor? What are the rules for fetching a copy of an object by exercising alink?3. Does the new, emerging practice of posting submittedmanuscripts on public servers constitute publication? Under what circumstancesshould ACM retain its "no scooping" policy? What about its "novel submission"policy?4. What notices should authors of submitted papers be required toinclude with their public-server postings? Should an accepted paper be removedfrom the author's host when copyright is transferred to ACM?5. Should changes and corrections create new versions of a workrather than replacing old versions? Will articles become more like software,requirement management by version control systems?6. Should high quality conferences with outstanding reputations beconsidered of equivalent quality to transactions and journals? (Conferencesreview for accept or reject under strict deadlines while journals review forrevisions that will improve a manuscript; do these differences matter?)7. Should there be an archiving fee, replacing the current practiceof page charges? Should uncited items be deleted from the archive after aminimum holding time? Should highly cited items be guaranteed a permanentplace in the archive?Answers to these questions are evolving as the field changes and we learn more.ACM's new, interim copyright policy statement and author's guide are attached asappendices.Publishers that learn to provide well structured knowledge through digitallibraries and easy-to-use tools will be the main survivors and successfulentrepreneurs in the new medium. They will need to develop new policiesconsistent with their evolving practices and their long-term vision.
