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.
