From mid-December through mid-October the PCHS Library  is open for researchers to drop in (see schedule below);  however,  appointments are strongly encouraged as they will allow our staff to better assist you with your research needs.

Please confirm our hours of operation before traveling long distances as they may be subject to change at any time.

Access to the museum is free for all members of the Passaic County Historical Society.  Non-members are required to pay the museum admission fee.  This entitles them to a museum tour and use of the library.

The PCHS Library encompasses a rich collection of materials related to the history of cities and towns within Passaic County as well as an extensive body of genealogical information on thousands of families who lived within the county.   The library contains approximately 2,800 books.  These include atlases, city directories, books by local authors, published genealogies, and local histories.   The library has a manuscript collection and thousands of family group sheets on file.
