I just realized that thinking of the CD-ROM as an alternative Proceedings isn't really a valid comparison. Generally, each paper in the Proceedings has far more detail than is given during the presentation, and may include graphics as well. Perhaps comparing the CD-ROM to the (expensive) audio tapes is much more valid. Further, the CD-ROM could include the Proceedings, graphics and all, in Adobe Acrobat form.
