WorldCat.org is the world's largest combined library catalog, listing over 1 billion items in 10,000 libraries, including about 75% of the materials in the UC Berkeley libraries. Also included are 30 million journal and magazine articles from the ArticleFirst, ERIC (education), and Medline databases.
WorldCat.org shows which nearby libraries own a particular item, and lets you generate or export citations, add your own notes or reviews, and save items in personalized lists. For all these reasons, we recently added a link to Worldcat.org on the library homepage.
