The largest collection of source materials for Chatham County genealogy and local history is maintained at the Chatham Community Library in Pittsboro, although both Wren Memorial Library in Siler City and the Goldston Library still maintain research collections of local interest.

CCHA has long supported the improvement of resources for local history and Chatham family research through donations of funds and materials to the local history area of the Chatham Community Library and continues to collaborate with the library staff to develop the local history-genealogy collection.
