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](doc/stat.htm). \[[WorldCat Web service: xISSN \[OCLC – WorldCat Affiliate tools\]: Home](https://xissn.worldcat.org/xissnadmin/index.htm?ref=lorcandempsey.net)\]
