The Felton Historical Museum (previously known as the Library Annex) is located at 18 Common Street, adjacent to the main library building, and is under the administration of the Board of Trustees.
As a collaboration between the library and the Brookfield Historical Commission, the Felton Historical Museum provides storage and display areas for historic materials, and also serves as a meeting space for multiple community groups.
Donations of local and historic material are always welcome.
Tours of the Annex may be offered during the library's regular open hours, but only as staff availability allows.

The Felton Historical Museum (FHM) is made possible by generous donations to the Friends of the Library as well as the ongoing support of Brookfield voters and library patrons.
In 2018, with help from the Friends of the Library, the property at 18 Common Street was leased by the Merrick Public Library from Rudy and Sarah Heller, owners of the Tip Top Country Store on Central Street in Brookfield.
In 2021, after three years of leasing the property, Brookfield residents voted in favor of purchasing 18 Common Street during Brookfield’s Annual Town Meeting.
In 2025, renovations began on the Barn and Wood Room at the FHM. When finished, the space will offer ADA accessible program and meeting space for the library and the community.
Coming Soon: The Felton Historical Museum will be dedicated to several of its benevolent advocates, including Wilfred & Barbara Steadman and Rudy & Sarah Heller.
