Yale University Library was designated a federal depository library in 1859. It became a selective depository when the program was reorganized by federal public law in 1962, meaning that it does not receive all materials disseminated through the Federal Depository Library Program (FDLP) but instead selects a subset of those materials.
Strengths of the FDLP collection include congressional and executive branch documents, economics, international relations and diplomacy, labor, history, public policy and social issues, and statistical publications. The collection includes materials from 1789 to the present.
The Yale Law Library is also a U.S. federal depository library.
