Drawings are postscript files, not meeting international standards, but at least designed to go across platforms. Images, or rather the real archival forms, consist of the best available slides, which are being digitized. Much of the catalog material exists in database form--a form that the average user could use, manipulate, and display on a personal computer, but only at great cost. Thus, this is where the concession comes in: All of this rich, well-marked-up information is stripped of much of its content; the images are converted into bit-maps and the text into small formatted chunks. All this information can then be imported into HyperCard and run on a mid-range Macintosh, which is what Perseus users have. This fact has made it possible for Perseus to attain wide use fairly rapidly. Without those archival forms the HyperCard version being demonstrated could not be made easily, and the project could not have the potential to move to other forms and machines and software as they appear, none of which information is in Perseus on the CD. Of the numerous multimedia aspects of Perseus, MYLONAS focused on the textual. Part of what makes Perseus such a pleasure to use, MYLONAS said, is this effort at seamless integration and the ability to move around both visual and textual material. Perseus also made the decision not to attempt to interpret its material any more than one interprets by selecting. But, MYLONAS emphasized, Perseus is not courseware: No syllabus exists. There is no effort to define how one teaches a topic using Perseus, although the project may eventually collect papers by people who have used it to teach. Rather, Perseus aims to provide primary material in a kind of electronic library, an electronic sandbox, so to say, in which students and scholars who are working on this material can explore by themselves. With that, MYLONAS demonstrated Perseus, beginning with the Perseus gateway, the first thing one sees upon opening Perseus--an effort in part to solve the contextualizing problem--which tells the user what the system contains.
