Anarchy in the MARC Records?

The headline in the Chronicle of Higher Ed. reads An Upstart Web Catalog Challenges an Academic-Library Giant. The story is about a 21-year-old named Aaron Swartz who is taking on WorldCat by building a free online book catalog that anyone can update, like Wikipedia. The project, Open Library, is set to go live in early March with records on 20 million books. Mr. Swartz also wants to integrate his database with Wikipedia so that a citation of a book on Wikipedia links to the book's page on Open Library. Another idea is to integrate Open Library with LibraryThing, a site that helps people catalog and share their own books.
