of data, 4) dissemination of research findings, and 5) curriculum development and instruction. The extent to which computation currently permeates aspects of scholarly communication represents a viable indicator of the prospects for electronic texts.

The discussion of current practice is balanced by an analysis of key trends in the scholarly use of information technology. These include the trends toward end-user computing and connectivity, which provide a framework for forecasting the use of electronic texts through this millennium. The presentation concludes with a summary of the ways in which the nonscientific scholarly community can be expected to use electronic texts, and the implications of that use for information providers.

Susan VECCIA and Joanne FREEMAN Electronic Archives for the Public:

Use of American Memory in Public and

School Libraries

This joint discussion focuses on nonscholarly applications of electronic library materials, specifically addressing use of the Library of Congress American Memory (AM) program in a small number of public and school libraries throughout the United States. AM consists of selected Library of Congress primary archival materials, stored on optical media (CD-ROM/videodisc), and presented with little or no editing. Many collections are accompanied by electronic introductions and user’s guides offering background information and historical context. Collections represent a variety of formats including photographs, graphic arts, motion pictures, recorded sound, music, broadsides and manuscripts, books, and pamphlets.

In 1991, the Library of Congress began a nationwide evaluation of AM in different types of institutions. Test sites include public libraries, elementary and secondary school libraries, college and university libraries, state libraries, and special libraries. Susan VECCIA and Joanne FREEMAN will discuss their observations on the use of AM by the nonscholarly community, using evidence gleaned from this ongoing evaluation effort.

VECCIA will comment on the overall goals of the evaluation project, and the types of public and school libraries included in this study. Her comments on nonscholarly use of AM will focus on the public library as a cultural and community institution, often bridging the gap between formal and informal education. FREEMAN will discuss the use of AM in school libraries. Use by students and teachers has revealed some broad questions about the use of electronic resources, as well as definite benefits gained by the “nonscholar.” Topics will include the problem of grasping content and context in an electronic environment, the stumbling blocks created by “new” technologies, and the unique skills and interests awakened through use of electronic resources.

SESSION II

Elli MYLONAS The Perseus Project: Interactive Sources and

Studies in Classical Greece

The Perseus Project (5) has just released Perseus 1.0, the first publicly available version of its hypertextual database of multimedia materials on classical Greece. Perseus is designed to be used by a wide audience, comprised of readers at the student and scholar levels. As such, it must be able to locate information using different strategies, and it must contain enough detail to serve the different needs of its users. In addition, it must be delivered so that it is affordable to its target audience. [These problems and the solutions we chose are described in Mylonas, “An Interface to Classical Greek Civilization,” JASIS 43:2, March 1992.]

In order to achieve its objective, the project staff decided to make a conscious separation between selecting and converting textual, database, and image data on the one hand, and putting it into a delivery system on the other. That way, it is possible to create the electronic data without thinking about the restrictions of the delivery system. We have made a great effort to choose system-independent formats for our data, and to put as much thought and work as possible into structuring it so that the translation from paper to electronic form will enhance the value of the data. [A discussion of these solutions as of two years ago is in Elli Mylonas, Gregory Crane, Kenneth Morrell, and D. Neel Smith, “The Perseus Project: Data in the Electronic Age,” in Accessing Antiquity: The Computerization of Classical Databases, J. Solomon and T. Worthen (eds.), University of Arizona Press, in press.]

Much of the work on Perseus is focused on collecting and converting the data on which the project is based. At the same time, it is necessary to provide means of access to the information, in order to make it usable, and them to investigate how it is used. As we learn more about what students and scholars from different backgrounds do with Perseus, we can adjust our data collection, and also modify the system to accommodate them. In creating a delivery system for general use, we have tried to avoid favoring any one type of use by allowing multiple forms of access to and navigation through the system.

The way text is handled exemplifies some of these principles. All text in Perseus is tagged using SGML, following the guidelines of the Text Encoding Initiative (TEI). This markup is used to index the text, and process it so that it can be imported into HyperCard. No SGML markup remains in the text that reaches the user, because currently it would be too expensive to create a system that acts on SGML in real time. However, the regularity provided by SGML is essential for verifying the content of the texts, and greatly speeds all the processing performed on them. The fact that the texts exist in SGML ensures that they will be relatively easy to port to different hardware and software, and so will outlast the current delivery platform. Finally, the SGML markup incorporates existing canonical reference systems (chapter, verse, line, etc.); indexing and navigation are based on these features. This ensures that the same canonical reference will always resolve to the same point within a text, and that all versions of our texts, regardless of delivery platform (even paper printouts) will function the same way.

In order to provide tools for users, the text is processed by a morphological analyzer, and the results are stored in a database. Together with the index, the Greek-English Lexicon, and the index of all the English words in the definitions of the lexicon, the morphological analyses comprise a set of linguistic tools that allow users of all levels to work with the textual information, and to accomplish different tasks. For example, students who read no Greek may explore a concept as it appears in Greek texts by using the English-Greek index, and then looking up works in the texts and translations, or scholars may do detailed morphological studies of word use by using the morphological analyses of the texts. Because these tools were not designed for any one use, the same tools and the same data can be used by both students and scholars.

Eric CALALUCA

Chadwyck-Healey embarked last year on two distinct yet related full-text humanities database projects.

The English Poetry Full-Text Database and the Patrologia Latina Database represent new approaches to linguistic research resources. The size and complexity of the projects present problems for electronic publishers, but surmountable ones if they remain abreast of the latest possibilities in data capture and retrieval software techniques.

The issues which required address prior to the commencement of the projects were legion:

 

1. Editorial selection (or exclusion) of materials in each

database

 

2. Deciding whether or not to incorporate a normative encoding

structure into the databases?

A. If one is selected, should it be SGML?

B. If SGML, then the TEI?

 

3. Deliver as CD-ROM, magnetic tape, or both?

 

4. Can one produce retrieval software advanced enough for the

postdoctoral linguist, yet accessible enough for unattended

general use? Should one try?

 

5. Re fair and liberal networking policies, what are the risks to

an electronic publisher?

 

6. How does the emergence of national and international education

networks affect the use and viability of research projects

requiring high investment? Do the new European Community

directives concerning database protection necessitate two

distinct publishing projects, one for North America and one for

overseas?

From new notions of “scholarly fair use” to the future of optical media, virtually every issue related to electronic publishing was aired. The result is two projects which have been constructed to provide the quality research resources with the fewest encumbrances to use by teachers and private scholars.

In spring 1988 the editors of the papers of George Washington, John Adams, Thomas Jefferson, James Madison, and Benjamin Franklin were approached by classics scholar David Packard on behalf of the Packard Humanities Foundation with a proposal to produce a CD-ROM edition of the complete papers of each of the Founding Fathers. This electronic edition will supplement the published volumes, making the documents widely available to students and researchers at reasonable cost. We estimate that our CD-ROM edition of Washington’s Papers will be substantially completed within the next two years and ready for publication. Within the next ten years or so, similar CD-ROM editions of the Franklin, Adams, Jefferson, and Madison papers also will be available. At the Library of Congress’s session on technology, I would like to discuss not only the experience of the Washington Papers in producing the CD-ROM edition, but the impact technology has had on these major editorial projects. Already, we are editing our volumes with an eye to the material that will be readily available in the CD-ROM edition. The completed electronic edition will provide immense possibilities for the searching of documents for information in a way never possible before. The kind of technical innovations that are currently available and on the drawing board will soon revolutionize historical research and the production of historical documents. Unfortunately, much of this new technology is not being used in the planning stages of historical projects, simply because many historians are aware only in the vaguest way of its existence. At least two major new historical editing projects are considering microfilm editions, simply because they are not aware of the possibilities of electronic alternatives and the advantages of the new technology in terms of flexibility and research potential compared to microfilm. In fact, too many of us in history and literature are still at the stage of struggling with our PCs. There are many historical editorial projects in progress presently, and an equal number of literary projects. While the two fields have somewhat different approaches to textual editing, there are ways in which electronic technology can be of service to both.

Since few of the editors involved in the Founding Fathers CD-ROM editions are technical experts in any sense, I hope to point out in my discussion of our experience how many of these electronic innovations can be used successfully by scholars who are novices in the world of new technology. One of the major concerns of the sponsors of the multitude of new scholarly editions is the limited audience reached by the published volumes. Most of these editions are being published in small quantities and the publishers’ price for them puts them out of the reach not only of individual scholars but of most public libraries and all but the largest educational institutions. However, little attention is being given to ways in which technology can bypass conventional publication to make historical and literary documents more widely available.

What attracted us most to the CD-ROM edition of The Papers of George Washington was the fact that David Packard’s aim was to make a complete edition of all of the 135,000 documents we have collected available in an inexpensive format that would be placed in public libraries, small colleges, and even high schools. This would provide an audience far beyond our present 1,000-copy, $45 published edition. Since the CD-ROM edition will carry none of the explanatory annotation that appears in the published volumes, we also feel that the use
