Sites on specific theatres:

The preservation movement seems to have been gaining ground these last few years. The "tear it down" mentality of many communities in the '50s, '60s, and '70s has given way to a renewed sense of history, of time and place. Many communities have restored and revived the old Theatres and Houses that once defined an evening's entertainment, and proudly display them on the Web for others to enjoy. As a dedicated preservationist and silent film fan, I'm happy to list the theatres I find that may or may not be on The Movie Palace Locator. The interiors of these places still fills one with a sense of awe, evoking romantic dreams of a time when movie-going was an event...
