(You need to register there and have a photo taken if you want to work on-site.) The library's books and journals are also available through interlibrary loan. Go to for more info.

NIH Library

This is a different library than the NLM. It is located in Building 10 on the NIH campus down an obscure hallway. It has open stacks, longer hours than the NLM, and is well stocked with journals since it is the library used by the NIH staff. It is open to the public and well worth the trip if you are doing your own ITP research. Go to for more info.
