Whether or not this collection of hypermedia works is ground breaking, historic etc is, of course, a matter which will be decided in the future. My prediction, based on my sense of the inherent value of many of the works, is that Volume 21 has made a place for itself in the chronicles of early hypermedia literary art. There are over 50 works in Volume 21. Most of the pieces here owe considerable debt to the editors, who in many cases were responsible for integration of media. There is a tremendous variety of artistic intentions and tonalities.
Some works are very kinetic, some angry.
Some are lyric, even elegiac. Some provide multiple opportunities for reader interaction. Others are artistically constraining. Some confine themselves to two. Sometimes the relationships among media are harmonious, illustrative.
