Resource sharing and document delivery in the Network of the National Library of Medicine (NNLM) is accomplished through DOCLINE, the National Library of Medicine's automated interlibrary loan (ILL) request routing and referral system.

The purpose of the system is to provide improved document delivery service among libraries in the NNLM by linking journal holdings to efficiently route the requests to potential lending libraries on behalf of the borrower. Requests can be created, routed, received, and filled in this system. DOCLINE participants can also check the status of requests for which they are either the borrowing or lending library.

DOCLINE serves over 2,700 U.S., Canadian and Mexican medical libraries at no cost. Some selected national and major medical libraries in other countries also have DOCLINE access. Health sciences libraries and libraries at institutions with a health sciences mission are eligible to apply for access to the DOCLINE system.
