WorldCat Partner Program
Enhance your Web site or online application with WorldCat lookup information for library-owned content.

Add the power of WorldCat—the world's most comprehensive database of library-owned content and services—to your Web site or online service. Whether you're a bibliophile maintaining a small fan site, a book publisher with a Web store, or a major organization offering e-commerce, database or search functionality, you can help users connect to related information through the WorldCat.org interface.

Provide Web links to WorldCat Web results

(Free to all)

Let your Web site's users locate a specific book or serial, or a range of materials connected to subject, title and author keywords, in a library near them. Using simple URL syntaxes that embed keywords or ISBN or ISSN standard numbers, you can publish or dynamically enable Web links to WorldCat search results or item records. (Syntaxes include specifications for geographic limiting and types of information displayed.)
