ISIL

International Standard Identifier for Libraries and Related Organizations (ISO 15511)

The purpose of ISIL is to define and promote the use of a set of standard identifiers for the unique identification of libraries and related organizations with a minimum impact on already existing systems.

ISIL identifiers are assigned on request by the ISIL allocation agencies listed below. Libraries and other organisations may request ISILs also to their subordinate units such as branch libraries if and when necessary.

Both ISIL and ISNI (International Standard Name Identifier - ISO 27729) can be used to identify libraries, but they have different functions. ISNI is used in cataloguing for unique identification, whereas ISIL is used in circulation and interlibrary lending.
