Our Openly colleagues have added a new service, xISSN, alongside xISBN.
The xISSN Web service supplies ISSNs and other information associated with serial publications represented in WorldCat. Submit an ISSN to this service, and it returns a list of related ISSNs and selected metadata. The service is based on WorldCat, the world's largest network of library content and services. The current xISSN database covers 575,573 ISSNs. [WorldCat Web service: xISSN [OCLC - WorldCat Affiliate tools]: Home]
