The War Memorial Library in Hudson is a non-profit registered charity providing a subscription library of printed and digital materials, primarily in the English language, to the residents of Hudson, Quebec and surrounding communities. Operated by volunteers, the Library is self-financing through membership fees, donations and fund raising activities. The Library in turn donates, to local charities, funds in excess of its own needs. The building and the Library serve as a memorial to those in Hudson who served in the Canadian Armed Forces.
Hudson’s two libraries are the Como Lending Library and the War Memorial Library. The first one was founded in 1849 and though most of it was destroyed in a fire in 1988, it is still in operation at the rebuilt St. Mary’s Parish Hall. St. Mary's Anglican Church was built in 1867 in Gothic Revival Style (but without the buttresses).
