NOTICE: The Cincinnati History Library and Archives is updating access to their website and online catalog. Until the new website is up and running, the links to their indexes and book, photo, manuscript and journal catalogs from this page are not working.
Visiting the Library
The Cincinnati History Library and Archives (CHLA) is free and open to the public. Park in the Cincinnati Museum Center’s lot for a fee unless you’re a member, or park on the street without charge. CHLA is located on the Museum Center's mezzanine level. It is required that you contact the library before visiting, due to limited hours and since a significant portion of their collection is housed offsite and what you want may need to be retrieved before you can access it.  Contact: library@cincymuseum.org.
Hamilton County Genealogical Records in CHLA
Founded in 1831, CHLA has one of the most significant regional historical collections in the United States, with thousands of books, pamphlets, periodicals, ephemera, manuscripts, architectural drawings, photographs, maps, business records, broadcast tapes and special collections.
Online Catalog
Cincinnati History Library and Archives has a new inclusive search engine for their collections where the public can search not only books, journals, and manuscripts but also museum artifacts. Many of the collections are “coming soon” but genealogists can already search published works, manuscripts, photographs, digital journals, and the local history index.  Many items are not catalogued, so contact the library for more information or to set up an appointment to visit.
