Using the API

The Classify Web Service is an experimental web service from the OCLC Office of Research. The web services enables users to submit an identifier such as an ISBN, ISSN, OCLC Number, LCCN, or UPC and retrieve information about the classification of that work in Dewey and Library of Congress Classifications. The service also retrieves FAST headings. In addition to the web service, a web interface to Classify is also available.
