The Historic Sites Committee of the London Public Library Board identifies and marks historic buildings, places, and people of local significance. This Walking Guide provides brief histories of the 49 sites marked by the committee, 1970-2000. Where buildings have been subsequently demolished, the plaques have been re-mounted in the Ivey Family London Room at the Central Library, 251 Dundas Street. At the time of publication, a few plaques are missing from their sites, and the committee is working to replace them.
