The National Library of Medicine (NLM) provides DOCLINE Elegibility Guidelines which detail the requirements for becoming a DOCLINE participant.
You are eligible to become a DOCLINE participant if your library is currently subscribed to a minimum of 25 titles in the health sciences, which you are willing to lend through DOCLINE.
The eligibility guidelines are meant to reinforce the role of DOCLINE as a resource sharing system. They are meant to preclude libraries from joining with the intent of only ever using DOCLINE to borrow. They are not meant to prevent libraries with small collections or limited resources from participating. If you are interested in DOCLINE but think that you may not meet the eligibility guidelines, you should contact the DOCLINE Group to discuss your situation.
Within the guidelines that DOCLINE participants should be willing to do some lending through DOCLINE, each participating library is entitled to set its own ILL policies, including restricting the scope of its lending and setting ILL fees and similar policies. Commercial document delivery is prohibited in DOCLINE.
If you are interested in joining DOCLINE, contact the DOCLINE Group. The coordinator will outline the registration process and answer any questions you might have.
