Waterloo Library is a heritage listed building in the inner city suburb of Waterloo. The building was originally the Waterloo Town Hall, designed by John Smedley and built in 1881 in the Victorian Italianate style. It is historically significant as evidence of the small inner city council areas which were subsumed into larger municipalities.
David Scott Mitchell (1836 – 1907) was a book collector. He offered his collection of Australiana to the people of New South Wales on the condition that a new building be erected to house the collection as a separate library.
Work on the Mitchell Wing started in 1906 and was completed in 1910. It houses the Mitchell Library reading rooms, work areas and galleries. It is part of the State Library of NSW.
