When you request items via Interlibrary Loan, if they cannot be found within the libraries of the UC system they often get sent to an international network of health sciences libraries through a service called DOCLINE. Managed by the National Library of Medicine, DOCLINE lets libraries share their less-commonly-held journals. Yesterday DOCLINE handled its 30 millionth transaction – it was a request from Saint Louis University to the University of Nevada. Quiet and largely unknown to end-users, it truly is a model of reciprocity which leverages the resources of libraries nationwide. And you just thought you were getting an article!
