(new and improved RLF tool)
The Location Request tool takes an OCLC number and queries OCLC and/or HathiTrust. The tool is good for searching for single-volume monographs. For multi-volume monographs or serials, the tool is most useful if nothing is held at an RLF. If an OCLC number is found at an RLF or HathiTrust, more checking will be necessary to determine which volume(s) is/are actually held.
