Part 2

After welcoming participants on behalf of the Library of Congress, American Memory (AM), and the National Demonstration Lab, Prosser GIFFORD, director for scholarly programs, Library of Congress, located the origin of the Workshop on Electronic Texts in a conversation he had had considerably more than a year ago with Carl FLEISCHHAUER concerning some of the issues faced by AM. On the assumption that numerous other people were asking the same questions, the decision was made to bring together as many of these people as possible to ask the same questions together. In a deeper sense, GIFFORD said, the origin of the Workshop lay in the desire of the current Librarian of Congress, James H. Billington, to make the collections of the Library, especially those offering unique or unusual testimony on aspects of the American experience, available to a much wider circle of users than those few people who can come to Washington to use them. This meant that the emphasis of AM, from the outset, has been on archival collections of the basic material, and on making these collections themselves available, rather than selected or heavily edited products.

From AM's emphasis followed the questions with which the Workshop began: who will use these materials, and in what form will they wish to use them. But an even larger issue deserving mention, in GIFFORD's view, was the phenomenal growth in Internet connectivity. He expressed the hope that the prospect of greater interconnectedness than ever before would lead to: 1) much more cooperative and mutually supportive endeavors; 2) development of systems of shared and distributed responsibilities to avoid duplication and to ensure accuracy and preservation of unique materials; and 3) agreement on the necessary standards and development of the appropriate directories and indices to make navigation straightforward among the varied resources that are, and increasingly will be, available. In this connection, GIFFORD requested that participants reflect from the outset upon the sorts of outcomes they thought the Workshop might have. Did those present constitute a group with sufficient common interests to propose a next step or next steps, and if so, what might those be? They would return to these questions the following afternoon.

Carl FLEISCHHAUER, coordinator, American Memory, Library of Congress, emphasized that he would attempt to represent the people who perform some of the work of converting or preparing materials and that the core of the Workshop had to do with preparation and production. FLEISCHHAUER then drew a distinction between the long term, when many things would be available and connected in the ways that GIFFORD described, and the short term, in which AM not only has wrestled with the issue of what is the best course to pursue but also has faced a variety of technical challenges.

FLEISCHHAUER remarked AM's endeavors to deal with a wide range of library formats, such as motion picture collections, sound-recording collections, and pictorial collections of various sorts, especially collections of photographs. In the course of these efforts, AM kept coming back to textual materials--manuscripts or rare printed matter, bound materials, etc. Text posed the greatest conversion challenge of all. Thus, the genesis of the Workshop, which reflects the problems faced by AM. These problems include physical problems. For example, those in the library and archive business deal with collections made up of fragile and rare manuscript items, bound materials, especially the notoriously brittle bound materials of the late nineteenth century. These are precious cultural artifacts, however, as well as interesting sources of information, and LC desires to retain and conserve them. AM needs to handle things without damaging them. Guillotining a book to run it through a sheet feeder must be avoided at all costs.

Beyond physical problems, issues pertaining to quality arose. For example, the desire to provide users with a searchable text is affected by the question of acceptable level of accuracy. One hundred percent accuracy is tremendously expensive. On the other hand, the output of optical character recognition (OCR) can be tremendously inaccurate. Although AM has attempted to find a middle ground, uncertainty persists as to whether or not it has discovered the right solution.

Questions of quality arose concerning images as well. FLEISCHHAUER contrasted the extremely high level of quality of the digital images in the Cornell Xerox Project with AM's efforts to provide a browse-quality or access-quality image, as opposed to an archival or preservation image. FLEISCHHAUER therefore welcomed the opportunity to compare notes.

FLEISCHHAUER observed in passing that conversations he had had about networks have begun to signal that for various forms of media a determination may be made that there is a browse-quality item, or a distribution-and-access-quality item that may coexist in some systems with a higher quality archival item that would be inconvenient to send through the network because of its size. FLEISCHHAUER referred, of course, to images more than to searchable text.

As AM considered those questions, several conceptual issues arose: ought AM occasionally to reproduce materials entirely through an image set, at other times, entirely through a text set, and in some cases, a mix? There probably would be times when the historical authenticity of an artifact would require that its image be used. An image might be desirable as a recourse for users if one could not provide 100-percent accurate text. Again, AM wondered, as a practical matter, if a distinction could be drawn between rare printed matter that might exist in multiple collections--that is, in ten or fifteen libraries. In such cases, the need for perfect reproduction would be less than for unique items. Implicit in his remarks, FLEISCHHAUER conceded, was the admission that AM has been tilting strongly towards quantity and drawing back a little from perfect quality. That is, it seemed to AM that society would be better served if more things were distributed by LC--even if they were not quite perfect--than if fewer things, perfectly represented, were distributed. This was stated as a proposition to be tested, with responses to be gathered from users.

In thinking about issues related to reproduction of materials and seeing other people engaged in parallel activities, AM deemed it useful to convene a conference. Hence, the Workshop. FLEISCHHAUER thereupon surveyed the several groups represented: 1) the world of images (image users and image makers); 2) the world of text and scholarship and, within this group, those concerned with language--FLEISCHHAUER confessed to finding delightful irony in the fact that some of the most advanced thinkers on computerized texts are those dealing with ancient Greek and Roman materials; 3) the network world; and 4) the general world of library science, which includes people interested in preservation and cataloging.

FLEISCHHAUER concluded his remarks with special thanks to the David and Lucile Packard Foundation for its support of the meeting, the American Memory group, the Office for Scholarly Programs, the National Demonstration Lab, and the Office of Special Events. He expressed the hope that David Woodley Packard might be able to attend, noting that Packard's work and the work of the foundation had sponsored a number of projects in the text area.

SESSION I. CONTENT IN A NEW FORM: WHO WILL USE IT AND WHAT WILL THEY DO?

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ DALY * Acknowledgements * A new Latin authors disk * Effects of the new technology on previous methods of research * +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Serving as moderator, James DALY acknowledged the generosity of all the presenters for giving of their time, counsel, and patience in planning the Workshop, as well as of members of the American Memory project and other Library of Congress staff, and the David and Lucile Packard Foundation and its executive director, Colburn S. Wilbur.

DALY then recounted his visit in March to the Center for Electronic Texts in the Humanities (CETH) and the Department of Classics at Rutgers University, where an old friend, Lowell Edmunds, introduced him to the department's IBYCUS scholarly personal computer, and, in particular, the new Latin CD-ROM, containing, among other things, almost all classical Latin literary texts through A.D. 200. Packard Humanities Institute (PHI), Los Altos, California, released this disk late in 1991, with a nominal triennial licensing fee.

Playing with the disk for an hour or so at Rutgers brought home to DALY at once the revolutionizing impact of the new technology on his previous methods of research. Had this disk been available two or three years earlier, DALY contended, when he was engaged in preparing a commentary on Book 10 of Virgil's Aeneid for Cambridge University Press, he would not have required a forty-eight-square-foot table on which to spread the numerous, most frequently consulted items, including some ten or twelve concordances to key Latin authors, an almost equal number of lexica to authors who lacked concordances, and where either lexica or concordances were lacking, numerous editions of authors antedating and postdating Virgil.

Nor, when checking each of the average six to seven words contained in the Virgilian hexameter for its usage elsewhere in Virgil's works or other Latin authors, would DALY have had to maintain the laborious mechanical process of flipping through these concordances, lexica, and editions each time. Nor would he have had to frequent as often the Milton S. Eisenhower Library at the Johns Hopkins University to consult the Thesaurus Linguae Latinae. Instead of devoting countless hours, or the bulk of his research time, to gathering data concerning Virgil's use of words, DALY--now freed by PHI's Latin authors disk from the tyrannical, yet in some ways paradoxically happy scholarly drudgery-- would have been able to devote that same bulk of time to analyzing and interpreting Virgilian verbal usage.

Citing Theodore Brunner, Gregory Crane, Elli MYLONAS, and Avra MICHELSON, DALY argued that this reversal in his style of work, made possible by the new technology, would perhaps have resulted in better, more productive research. Indeed, even in the course of his browsing the Latin authors disk at Rutgers, its powerful search, retrieval, and highlighting capabilities suggested to him several new avenues of research into Virgil's use of sound effects. This anecdotal account, DALY maintained, may serve to illustrate in part the sudden and radical transformation being wrought in the ways scholars work.

Avra MICHELSON, Archival Research and Evaluation Staff, National Archives and Records Administration (NARA), argued that establishing who will use electronic texts and what they will use them for involves a consideration of both information technology and scholarship trends. This consideration includes several elements related to scholarship and technology: 1) the key trends in information technology that are most relevant to scholarship; 2) the key trends in the use of currently available technology by scholars in the nonscientific community; and 3) the relationship between these two very distinct but interrelated trends. The investment in understanding this relationship being made by information providers, technologists, and public policy developers, as well as by scholars themselves, seems to be pervasive and growing, MICHELSON contended. She drew on collaborative work with Jeff Rothenberg on the scholarly use of technology.

MICHELSON sought to place the phenomenon of electronic texts within the context of broader trends within information technology and scholarly communication. She argued that electronic texts are of most use to researchers to the extent that the researchers' working context (i.e., their relevant bibliographic sources, collegial feedback, analytic tools, notes, drafts, etc.), along with their field's primary and secondary sources, also is accessible in electronic form and can be integrated in ways that are unique to the on-line environment.

Evaluation of the prospects for the use of electronic texts includes two elements: 1) an examination of the ways in which researchers currently are using electronic texts along with other electronic resources, and 2) an analysis of key information technology trends that are affecting the long-term conduct of scholarly communication. MICHELSON limited her discussion of the use of electronic texts to the practices of humanists and noted that the scientific community was outside the panel's overview.

MICHELSON examined the nature of the current relationship of electronic texts in particular, and electronic resources in general, to what she maintained were, essentially, five processes of scholarly communication in humanities research. Researchers 1) identify sources, 2) communicate with their colleagues, 3) interpret and analyze data, 4) disseminate their research findings, and 5) prepare curricula to instruct the next generation of scholars and students. This examination would produce a clearer understanding of the synergy among these five processes that fuels the tendency of the use of electronic resources for one process to stimulate its use for other processes of scholarly communication.

For the first process of scholarly communication, the identification of sources, MICHELSON remarked the opportunity scholars now enjoy to supplement traditional word-of-mouth searches for sources among their colleagues with new forms of electronic searching. So, for example, instead of having to visit the library, researchers are able to explore descriptions of holdings in their offices. Furthermore, if their own institutions' holdings prove insufficient, scholars can access more than 200 major American library catalogues over Internet, including the universities of California, Michigan, Pennsylvania, and Wisconsin. Direct access to the bibliographic databases offers intellectual empowerment to scholars by presenting a comprehensive means of browsing through libraries from their homes and offices at their convenience.

The second process of communication involves communication among scholars. Beyond the most common methods of communication, scholars are using E-mail and a variety of new electronic communications formats derived from it for further academic interchange. E-mail exchanges are growing at an astonishing rate, reportedly 15 percent a month. They currently constitute approximately half the traffic on research and education networks. Moreover, the global spread of E-mail has been so rapid that it is now possible for American scholars to use it to communicate with colleagues in close to 140 other countries.

Other new exchange formats created by scholars and operating on Internet include more than 700 conferences, with about 80 percent of these devoted to topics in the social sciences and humanities. The rate of growth of these scholarly electronic conferences also is astonishing. From l990 to l991, 200 new conferences were identified on Internet. From October 1991 to June 1992, an additional 150 conferences in the social sciences and humanities were added to this directory of listings. Scholars have established conferences in virtually every field, within every different discipline. For example, there are currently close to 600 active social science and humanities conferences on topics such as art and architecture, ethnomusicology, folklore, Japanese culture, medical education, and gifted and talented education. The appeal to scholars of communicating through these conferences is that, unlike any other medium, electronic conferences today provide a forum for global communication with peers at the front end of the research process.

Interpretation and analysis of sources constitutes the third process of scholarly communication that MICHELSON discussed in terms of texts and textual resources. The methods used to analyze sources fall somewhere on a continuum from quantitative analysis to qualitative analysis. Typically, evidence is culled and evaluated using methods drawn from both ends of this continuum. At one end, quantitative analysis involves the use of mathematical processes such as a count of frequencies and distributions of occurrences or, on a higher level, regression analysis. At the other end of the continuum, qualitative analysis typically involves nonmathematical processes oriented toward language interpretation or the building of theory. Aspects of this work involve the processing--either manual or computational--of large and sometimes massive amounts of textual sources, although the use of nontextual sources as evidence, such as photographs, sound recordings, film footage, and artifacts, is significant as well.

Scholars have discovered that many of the methods of interpretation and analysis that are related to both quantitative and qualitative methods are processes that can be performed by computers. For example, computers can count. They can count brush strokes used in a Rembrandt painting or perform regression analysis for understanding cause and effect. By means of advanced technologies, computers can recognize patterns, analyze text, and model concepts. Furthermore, computers can complete these processes faster with more sources and with greater precision than scholars who must rely on manual interpretation of data. But if scholars are to use computers for these processes, source materials must be in a form amenable to computer-assisted analysis. For this reason many scholars, once they have identified the sources that are key to their research, are converting them to machine-readable form. Thus, a representative example of the numerous textual conversion projects organized by scholars around the world in recent years to support computational text analysis is the TLG, the Thesaurus Linguae Graecae. This project is devoted to converting the extant ancient texts of classical Greece. (Editor's note: according to the TLG Newsletter of May l992, TLG was in use in thirty-two different countries. This figure updates MICHELSON's previous count by one.)

The scholars performing these conversions have been asked to recognize that the electronic sources they are converting for one use possess value for other research purposes as well. As a result, during the past few years, humanities scholars have initiated a number of projects to increase scholarly access to converted text. So, for example, the Text Encoding Initiative (TEI), about which more is said later in the program, was established as an effort by scholars to determine standard elements and methods for encoding machine-readable text for electronic exchange. In a second effort to facilitate the sharing of converted text, scholars have created a new institution, the Center for Electronic Texts in the Humanities (CETH). The center estimates that there are 8,000 series of source texts in the humanities that have been converted to machine-readable form worldwide. CETH is undertaking an international search for converted text in the humanities, compiling it into an electronic library, and preparing bibliographic descriptions of the sources for the Research Libraries Information Network's (RLIN) machine-readable data file. The library profession has begun to initiate large conversion projects as well, such as American Memory.

While scholars have been making converted text available to one another, typically on disk or on CD-ROM, the clear trend is toward making these resources available through research and education networks. Thus, the American and French Research on the Treasury of the French Language (ARTFL) and the Dante Project are already available on Internet. MICHELSON summarized this section on interpretation and analysis by noting that: 1) increasing numbers of humanities scholars in the library community are recognizing the importance to the advancement of scholarship of retrospective conversion of source materials in the arts and humanities; and 2) there is a growing realization that making the sources available on research and education networks maximizes their usefulness for the analysis performed by humanities scholars.

The fourth process of scholarly communication is dissemination of research findings, that is, publication. Scholars are using existing research and education networks to engineer a new type of publication: scholarly-controlled journals that are electronically produced and disseminated. Although such journals are still emerging as a communication format, their number has grown, from approximately twelve to thirty-six during the past year (July 1991 to June 1992). Most of these electronic scholarly journals are devoted to topics in the humanities. As with network conferences, scholarly enthusiasm for these electronic journals stems from the medium's unique ability to advance scholarship in a way that no other medium can do by supporting global feedback and interchange, practically in real time, early in the research process. Beyond scholarly journals, MICHELSON remarked the delivery of commercial full-text products, such as articles in professional journals, newsletters, magazines, wire services, and reference sources. These are being delivered via on-line local library catalogues, especially through CD-ROMs. Furthermore, according to MICHELSON, there is general optimism that the copyright and fees issues impeding the delivery of full text on existing research and education networks soon will be resolved.
