citation counts are readily demonstrable, whereas the on-line environment represents an ethereal medium to most academics.

LEBRON remarked several technical and behavioral barriers to electronic publishing, for instance, the problems in transmission created by special characters or by complex graphics and halftones. In addition, she noted economic limitations such as the storage costs of maintaining back issues and market or audience education.

Manuscripts cannot be uploaded to OJCCT, LEBRON explained, because it is not a bulletin board or E-mail, forms of electronic transmission of information that have created an ambience clouding people’s understanding of what the journal is attempting to do. OJCCT, which publishes peer-reviewed medical articles dealing with the subject of clinical trials, includes text, tabular material, and graphics, although at this time it can transmit only line illustrations.

Next, LEBRON described how AAAS and OCLC arrived at the subject of clinical trials: It is 1) a highly statistical discipline that 2) does not require halftones but can satisfy the needs of its audience with line illustrations and graphic material, and 3) there is a need for the speedy dissemination of high-quality research results. Clinical trials are research activities that involve the administration of a test treatment to some experimental unit in order to test its usefulness before it is made available to the general population. LEBRON proceeded to give additional information on OJCCT concerning its editor-in-chief, editorial board, editorial content, and the types of articles it publishes (including peer-reviewed research reports and reviews), as well as features shared by other traditional hard-copy journals.

Among the advantages of the electronic format are faster dissemination of information, including raw data, and the absence of space constraints because pages do not exist. (This latter fact creates an interesting situation when it comes to citations.) Nor are there any issues. AAAS’s capacity to download materials directly from the journal to a subscriber’s printer, hard drive, or floppy disk helps ensure highly accurate transcription. Other features of OJCCT include on-screen alerts that allow linkage of subsequently published documents to the original documents; on-line searching by subject, author, title, etc.; indexing of every single word that appears in an article; viewing access to an article by component (abstract, full text, or graphs); numbered paragraphs to replace page counts; publication in Science every thirty days of indexing of all articles published in the journal; typeset-quality screens; and Hypertext links that enable subscribers to bring up Medline abstracts directly without leaving the journal.

After detailing the two primary ways to gain access to the journal, through the OCLC network and Compuserv if one desires graphics or through the Internet if just an ASCII file is desired, LEBRON illustrated the speedy editorial process and the coding of the document using SGML tags after it has been accepted for publication. She also gave an illustrated tour of the journal, its search-and-retrieval capabilities in particular, but also including problems associated with scanning in illustrations, and the importance of on-screen alerts to the medical profession re retractions or corrections, or more frequently, editorials, letters to the editors, or follow-up reports. She closed by inviting the audience to join AAAS on 1 July, when OJCCT was scheduled to go on-line.

DISCUSSION Additional features of OJCCT

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

In the lengthy discussion that followed LEBRON’s presentation, these points emerged:

 

* The SGML text can be tailored as users wish.

 

* All these articles have a fairly simple document definition.

 

* Document-type definitions (DTDs) were developed and given to OJCCT

for coding.

 

* No articles will be removed from the journal. (Because there are

no back issues, there are no lost issues either. Once a subscriber

logs onto the journal he or she has access not only to the currently

published materials, but retrospectively to everything that has been

published in it. Thus the table of contents grows bigger. The date

of publication serves to distinguish between currently published

materials and older materials.)

 

* The pricing system for the journal resembles that for most medical

journals: for 1992, $95 for a year, plus telecommunications charges

(there are no connect time charges); for 1993, $110 for the

entire year for single users, though the journal can be put on a

local area network (LAN). However, only one person can access the

journal at a time. Site licenses may come in the future.

 

* AAAS is working closely with colleagues at OCLC to display

mathematical equations on screen.

 

* Without compromising any steps in the editorial process, the

technology has reduced the time lag between when a manuscript is

originally submitted and the time it is accepted; the review process

does not differ greatly from the standard six-to-eight weeks

employed by many of the hard-copy journals. The process still

depends on people.

 

* As far as a preservation copy is concerned, articles will be

maintained on the computer permanently and subscribers, as part of

their subscription, will receive a microfiche-quality archival copy

of everything published during that year; in addition, reprints can

be purchased in much the same way as in a hard-copy environment.

Hard copies are prepared but are not the primary medium for the

dissemination of the information.

 

* Because OJCCT is not yet on line, it is difficult to know how many

people would simply browse through the journal on the screen as

opposed to downloading the whole thing and printing it out; a mix of

both types of users likely will result.

PERSONIUS Developments in technology over the past decade The CLASS Project Advantages for technology and for the CLASS Project Developing a network application an underlying assumption of the project Details of the scanning process Print-on-demand copies of books Future plans include development of a browsing tool

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Lynne PERSONIUS, assistant director, Cornell Information Technologies for Scholarly Information Services, Cornell University, first commented on the tremendous impact that developments in technology over the past ten years—networking, in particular—have had on the way information is handled, and how, in her own case, these developments have counterbalanced Cornell’s relative geographical isolation. Other significant technologies include scanners, which are much more sophisticated than they were ten years ago; mass storage and the dramatic savings that result from it in terms of both space and money relative to twenty or thirty years ago; new and improved printing technologies, which have greatly affected the distribution of information; and, of course, digital technologies, whose applicability to library preservation remains at issue.

Given that context, PERSONIUS described the College Library Access and Storage System (CLASS) Project, a library preservation project, primarily, and what has been accomplished. Directly funded by the Commission on Preservation and Access and by the Xerox Corporation, which has provided a significant amount of hardware, the CLASS Project has been working with a development team at Xerox to develop a software application tailored to library preservation requirements. Within Cornell, participants in the project have been working jointly with both library and information technologies. The focus of the project has been on reformatting and saving books that are in brittle condition. PERSONIUS showed Workshop participants a brittle book, and described how such books were the result of developments in papermaking around the beginning of the Industrial Revolution. The papermaking process was changed so that a significant amount of acid was introduced into the actual paper itself, which deteriorates as it sits on library shelves.

One of the advantages for technology and for the CLASS Project is that the information in brittle books is mostly out of copyright and thus offers an opportunity to work with material that requires library preservation, and to create and work on an infrastructure to save the material. Acknowledging the familiarity of those working in preservation with this information, PERSONIUS noted that several things are being done: the primary preservation technology used today is photocopying of brittle material. Saving the intellectual content of the material is the main goal. With microfilm copy, the intellectual content is preserved on the assumption that in the future the image can be reformatted in any other way that then exists.

An underlying assumption of the CLASS Project from the beginning was that it would develop a network application. Project staff scan books at a workstation located in the library, near the brittle material. An image-server filing system is located at a distance from that workstation, and a printer is located in another building. All of the materials digitized and stored on the image-filing system are cataloged in the on-line catalogue. In fact, a record for each of these electronic books is stored in the RLIN database so that a record exists of what is in the digital library throughout standard catalogue procedures. In the future, researchers working from their own workstations in their offices, or their networks, will have access—wherever they might be—through a request server being built into the new digital library. A second assumption is that the preferred means of finding the material will be by looking through a catalogue. PERSONIUS described the scanning process, which uses a prototype scanner being developed by Xerox and which scans a very high resolution image at great speed. Another significant feature, because this is a preservation application, is the placing of the pages that fall apart one for one on the platen. Ordinarily, a scanner could be used with some sort of a document feeder, but because of this application that is not feasible. Further, because CLASS is a preservation application, after the paper replacement is made there, a very careful quality control check is performed. An original book is compared to the printed copy and verification is made, before proceeding, that all of the image, all of the information, has been captured. Then, a new library book is produced: The printed images are rebound by a commercial binder and a new book is returned to the shelf. Significantly, the books returned to the library shelves are beautiful and useful replacements on acid-free paper that should last a long time, in effect, the equivalent of preservation photocopies. Thus, the project has a library of digital books. In essence, CLASS is scanning and storing books as 600 dot-per-inch bit-mapped images, compressed using Group 4 CCITT (i.e., the French acronym for International Consultative Committee for Telegraph and Telephone) compression. They are stored as TIFF files on an optical filing system that is composed of a database used for searching and locating the books and an optical jukebox that stores 64 twelve-inch platters. A very-high-resolution printed copy of these books at 600 dots per inch is created, using a Xerox DocuTech printer to make the paper replacements on acid-free paper.

PERSONIUS maintained that the CLASS Project presents an opportunity to introduce people to books as digital images by using a paper medium. Books are returned to the shelves while people are also given the ability to print on demand—to make their own copies of books. (PERSONIUS distributed copies of an engineering journal published by engineering students at Cornell around 1900 as an example of what a print-on-demand copy of material might be like. This very cheap copy would be available to people to use for their own research purposes and would bridge the gap between an electronic work and the paper that readers like to have.) PERSONIUS then attempted to illustrate a very early prototype of networked access to this digital library. Xerox Corporation has developed a prototype of a view station that can send images across the network to be viewed.

The particular library brought down for demonstration contained two mathematics books. CLASS is developing and will spend the next year developing an application that allows people at workstations to browse the books. Thus, CLASS is developing a browsing tool, on the assumption that users do not want to read an entire book from a workstation, but would prefer to be able to look through and decide if they would like
