This past weekend several enhancements were made to the WorldCat Search API. This included:
The first enhancement makes it easier to determine which libraries hold a particular journal. For example - http://www.worldcat.org/webservices/catalog/content/libraries/issn/00991333?location=77062&wskey=[key] Will tell you what libraries near zip code 774062 have the Journal of Academic librarianship. You can also now perform this query using LCCN in standard number index. This enhancement is helpful for materials which lack an ISBN and OCLC Number.
The OCLC Developer Network supports the use of OCLC Web Services—a set of tools and APIs that expose data and services for WorldCat and our member libraries and partner institutions or companies. learn more »
