The Library of Congress welcomes researchers to its reading rooms and research centers. Appointments are optional, but encouraged to serve you best, ensure collection material is accessible during your visit and optimize your time at the Library. The Thomas Jefferson Building has reopened to visitors via timed, ticketed entry—learn how to obtain a timed-entry pass. Virtual events and online services continue to be available.
Research guides provide a starting point for researching legal topics and recommend relevant materials in the Law Library's collections and online. The Law Library creates research guides that range from animal and landlord-tenant law to instructions for compiling a federal legislative history. Established by Congress in 1832, the Law Library has a collection of over 2.9 million volumes spanning all systems and periods of law and covering all the nations of the world. Please note that although research guides are selective, inclusion of a site or resource does not constitute endorsement by the Law Library of Congress. None of the information in any of our research guides is legal advice. LC Bibliographies, Research Guides and Finding Aids page.
