The All Libraries tab in WorldCat.org will show libraries with a cataloging subscription with OCLC who have a holding on this record. However, Library types that don't usually allow patron access won't appear in this list, which may cause a mismatch between the holdings count and the number of libraries displayed. If you are a library that wants to appear anyway, contact OCLC Support with your Library name, OCLC Symbol, and contact information.
