Getting a library card is easy and free. Register for a library card on-site at one of the computer stations. After you register, present a photo ID (i.e. a state driver's license, state ID, passport, U.S. Military ID, or University ID) to a staff member at the Information Desk. NLM's General Collection is in a staff-access only area. You can borrow up to 50 items at a time per day with a library card through LocatorPlus. However, you must be at NLM to place requests for materials. If materials are in poor condition, we will provide a photocopy of the requested pages or you may be allowed to view the materials in the staff-access only area.
