NLM Reading Rooms, Services, and Hours

There are two reading rooms open to the public at the National Library of Medicine (NLM); the Main Reading Room and History of Medicine Division (HMD) Reading Room. The Main Reading Room has an extensive reference collection. The General Collection has books (1914-present), journals and serials (1871-present), and audiovisual materials.

The HMD Reading Room has book-length material printed before 1914, thousands of pamphlets and dissertations (post-1914), and all pre-1871 journals. See the HMD Reading Room for additional information on services and materials available to the public.

Getting a Library Card and Requesting Library Materials

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. 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. You can register for a library card on-site by presenting a photo ID (i.e. a state driver's license, state ID, passport, U.S. Military ID, or University ID).

Scanning and Wi-Fi

The scanners and Wi-Fi are available for free.  You can use scanners only for NLM materials. The scanners shut down at 4:55 p.m.

  • You must bring a flash drive to save your scanned documents. We have four high-speed scanners in the Main Reading Room. We may impose time limits, so that others can also use the scanner.
  • We have one microfilm/microfiche reader-printer in the Main Reading Room.
  • You can log in to the NIH-Guest-Network Wi-Fi and click "Accept." After you log in, you can use "On-site Access Only" materials.
