LibraryThing Founder Tim Spalding

Cambridge Information Group (CIG), parent company to Bowker and ProQuest, has made an equity investment in LibraryThing (, an online book-cataloging service and social-networking site. Under the terms of the agreement, CIG purchased a minority stake in LibraryThing, and also has designated Bowker as the exclusive worldwide distributor of LibraryThing for Libraries (LTFL). LTFL is LibraryThing’s flagship library product, which puts tags, recommendations and reviews directly into a library's catalog.
