Hi
OCLC is planing "a Wiki that complements WorldCat. People could add reviews, cover art, comments, etc. and relate these to bibliographic records (..). We hope the system is flexible enough so that people do (good) things we’re not expecting. We’d like the Wiki to be available anywhere WorldCat records are.":

Looks like competition - we should better cooperate with OCLC.
greetings, Jakob
