State Public Libraries

PublicLibraries.com has been promoting public libraries online since it launched in 1999. We provide directory listings for public libraries and their branch locations across the United States.

The listings are organized by state (or territory) and they contain the physical address, ZIP code, county and phone number for each library, along with the library system each branch belongs to. The listings were last updated in October 2026, and we welcome additions, updates, deletions and corrections.

Note that each state only contains listings for public libraries. Government libraries like the Library of Congress and academic libraries at colleges and universities are not included in the state listings. Also libraries at local elementary, middle or high schools are also not included.

We periodically receive requests for a copy of our entire database to be used for mailing lists or other purposes. We do not offer this service as most of the librarians we talk to prefer not to be included in mailing lists.

If you would like to make changes or corrections to our listings, you can use the contact us link at the bottom of the page.
