In 2016, BIFHSGO transferred the ownership and management of its Brian O'Regan Memorial Library holdings to the Ottawa Branch of the Ontario Genealogical Society (OBOGS).
The merged collections represent the membership research interests of both societies: Eastern Ontario and Western Quebec, and the British Isles.
The library is located in the Reference Room of the City of Ottawa Archives at 100 Tallwood Drive.
Book Lists: a selection of resources in the library
BIFHSGO continues to provide resources for the library in the form of volunteers and financial support for the acquisition of books and other resources. These resources include journals provided through membership or exchange arrangements. BIFHSGO has also provided a subscription to the British Newspaper Archives.
