Visit: Plan Onsite Research

What to Know Before You Go

Historical material may be consulted in the History of Medicine Reading Room between 8:30 a.m. and 5:00 p.m. EST Monday through Friday, except for Federal holidays. The last retrieval from the stacks is at 4:00 p.m.

Get a Library Card

To use NLM collections, you must have a library card. You can register for a library card on-site in the Library’s Main Reading Room by presenting a photo ID (i.e. a state driver’s license, state ID, passport, U.S. Military ID, or University ID). To use historical collections you must also register in the History of Medicine Reading Room.

Request and Pick up Historical Materials

When you are onsite, use your library card ID number to request material through the library catalog (LocatorPlus) at terminals in either the Main Reading Room or the History of Medicine Reading Room or through your own device via our wireless network. The catalog can be consulted remotely, but materials can only be requested while onsite.

History of Medicine staff retrieves historical material from the stacks on the hour from 9:00 a.m. to 4:00 p.m. (EST). Pick up historical material in the History of Medicine Reading Room. Historical material may not be taken out of the History of Medicine Reading Room. Books published after 1913 and journals after 1870 are retrieved in the Main Reading Room.

Before You Visit

  • Search the Library’s online catalogs and print a list of material to consult before coming to the Library.
  • Review the Information for Readers document which includes a Registration Form that you will be asked to fill out on arrival.
  • Review the Visit page for directions, hours, parking, and important security information.
  • Check the OPM Operating Status for weather-related closings.
