The U.S. business directories in this microfilm collection were published between 1902 and 1935. They are shelved in large cabinets in the Microform and Electronic Resources Center, in drawers labeled Business Group, following the miscellaneous reels. Since these particular business directories are listed on their own page in this guide, they are not included on the separate state pages.
Please note, not all business reels are listed below. Additional business reels may be found within the more general City Directories of the United States collection, listed under the respective state categories in this guide.
In the tables below, for Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, and Vermont, also see New England.
