What is a LIBID? What should I do if I have forgotten my LIBID?

A LIBID (Library ID) is a unique 6-letter code that identifies institutions in the National Library of Medicine's DOCLINE system.  A LIBID is required to place interlibrary loan requests with the National Library of Medicine (NLM).

If you have never placed interlibrary loan requests with NLM before and would like to learn more about doing so see the Interlibrary Loan page.

If you have forgotten your LIBID or are unsure whether your library has one, please use our contact form to inquire about your LIBID.
