Access telephone numbers from 1962 through The Library of Congress, which houses an extensive collection of current and non-current telephone directories for the United States and several foreign countries. This collection of white and yellow pages are available to the public.
As of 2015, pre-1976 telephone directories are available only in paper copies, except for those for the District of Columbia, Chicago and 14 states, which have been microfilmed. These 14 states are Alabama, Alaska, Arizona, Arkansas and California; Colorado, Connecticut, Delaware, Florida and Georgia; as well as Hawaii, Iowa, Maryland and Pennsylvania.
To request a paper telephone book, fill out a call slip in the Local History and Genealogy Reading Room, with "Telephone Directory" as the call number, town and state as title, and the year required as the volume number. To view telephone books in microfilm, go to the Reading Room at LJ 139B and access the self-serve microfilm collection. The Library of Congress continues to convert all pre-1976 telephone books into microfilm.
U.S. telephone directories from 1976 to 1995 are available only in microfilm. Telephone directories from 1996 to the present are considered current and are found on Deck 46 of the Main Reading Room, where they are filed alphabetically by state. This location also houses many current foreign telephone directories, which are arranged alphabetically by country.
