ERWAY explained that, under the old policy, to make a claim for a copyright for works that were published in electronic form, including software, one had to submit a paper copy of the first and last twenty pages of code--something that represented the work but did not include the entire work itself and had little value to anyone. As a temporary measure, LC has claimed the right to demand electronic versions of electronic publications. This measure entails a proactive role for the Library to say that it wants a particular electronic version. Publishers then have perhaps a year to submit it. But the real problem for LC is what to do with all this material in all these different formats. Will the Library mount it? How will it give people access to it? How does LC keep track of the appropriate computers, software, and media? The situation is so hard to control, ERWAY said, that it makes sense for each publishing house to maintain its own archive. But LC cannot enforce that either. GIFFORD acknowledged LESK's suggestion that establishing a priority offered the solution, albeit a fairly complicated one. But who maintains that register?, he asked. GRABER noted that LC does attempt to collect a Macintosh version and the IBM-compatible version of software. It does not collect other versions. But while true for software, BYRUM observed, this reply does not speak to materials, that is, all the materials that were published that were on somebody's microcomputer or driver tapes at a publishing office across the country. LC does well to acquire specific machine-readable products selectively that were intended to be machine-readable. Materials that were in machine-readable form at one time, BYRUM said, would be beyond LC's capability at the moment, insofar as attempting to acquire, organize, and preserve them are concerned--and preservation would be the most important consideration. In this connection, GIFFORD reiterated the need to work out some sense of distributive responsibility for a number of these issues, which inevitably will require significant cooperation and discussion. Nobody can do it all. LESK suggested that some publishers may look with favor on LC beginning to serve as a depository of tapes in an electronic manuscript standard. Publishers may view this as a service that they did not have to perform and they might send in tapes. However, SPERBERG-McQUEEN countered, although publishers have had equivalent services available to them for a long time, the electronic text archive has never turned away or been flooded with tapes and is forever sending feedback to the depositor. Some publishers do send in tapes.
