The National Library of Australia has agreed to add some 12 million bibliographic records to WorldCat, a database of cataloged items held in libraries, making these records visible to Web searchers worldwide. Australian libraries will use WorldCat to catalog, find, and share library materials. Australian libraries that contribute their current cataloging and holdings to the Australian National Bibliographic Database and WorldCat will become governing members of the OCLC cooperative. WorldCat contains more than 85 million records representing more than 1 billion items held in libraries worldwide. The Open WorldCat Program makes library records available on the open web through search engines and partner sites, and through WorldCat.org, the site and single search box used to discover items in the world’s library collections.
