Here's an interesting and helpful new resource called WorldCat Identities provided by WorldCat, the world's largest network of library content and services.
WorldCat Identities presents an "identity" or profile of a particular person or company based on information and associations stored in the WorldCat bibliographic database. Identities can include authors, musicians, actors, publilshers or film studios.
Try it out. Just type in your favorite author and get a page that lists a publication timeline, works by and about the chosen identity, related subject headings and genres, audience level, related identities, book jacket covers and more.
The site also features a ‘cloud tag’ of the top 100 identities.
