Is it true that the WorldCat API consistently does not return call numbers when accessed via the following sort of URL:
http://www.worldcat.org/webservices/catalog/content/464597226?wskey=[key] If so, then given an OCLC number is it possible get an LCCN, and if so, then how? If not, then I'm thinking of implementing the follow algorithm in order to get around the problem: * via API, query WorldCat using OCLC number * get result * parse for LCCN * query Library of Congress via Z39.50 for LCCN * get result * parse for call number Whatta think? -- Eric Morgan
