Twickenham Museum is a model example of a small museum which has used its website to display more materials and bzackground texts on local history than it can within the small space of its actual building. The site has an excellent section on the cinemas of Twickenham, from 1911 to 1981, including models of the Lyric Palace (opened 1911), the Palaceum (opened 1912), and the Gaiety (opened 1912).
A good source of information on early London cinemas is the London Project site, which has a database of all film venues in London before the First World War.
