WorldCat Search API

Nice for members of OCLC, WorldCat Search API (Web service).

The WorldCat Search API allows your application to search the WorldCat catalog—which indexes the collections of thousands of member libraries around the world—and retrieve:

• lists of bibliographic records, and individual records, for library-held items;
• information about WorldCat libraries that have cataloged a particular item; and
• direct links to those libraries' Web catalog records for the item, when available

Your application will allow users to discover books, videos, music, electronic content and more through WorldCat.

How the API works

• Send searches in OpenSearch or SRU CQL syntax
• Receive OpenSearch responses in RSS or Atom format
• Receive SRU responses in MARC XML or Dublin Core
• Receive MARC XML content for a single OCLC record
• Receive geographically-sorted library holdings information (each including the institution's name, location and a catalog link) within requests for single records
• Receive records in standard bibliographic citation formats (APA, Chicago, Harvard, MLA, and Turabian)
