Binkley and Lav
Here’s a bit from a blog posting by Peter Binkley from 2 March 2006, Holdings for All, written after an IRC exchange with Aaron Lav:
Aaron is after something similar, to have a Book Burro-like function that makes use of xISBN to look for other editions, and a FRBRish display that makes it easy to see how the various editions differ (if, for example, you start with the ISBN for the 1995 edition, the display makes it easy to see that the library has the 1980 edition at a different call number).
Binkley gives a few thoughts about how the implementation could be done.
