I spent three days in Columbus, Ohio. One day - about seven plus hours - was spent at the Columbus Metropolitan Library, where I went through microfilm of the three major Columbus newspapers. I searched the Columbus Dispatch, Columbus Citizen, and Ohio State Journal, and managed to find at least 15 or more articles / film reviews in each paper. I also found some Denishawn material, and a few nice movie advertisements. There was an index - incomplete, as it turned out - to the early years of the Ohio State Journal, and this lead me to about half-a-dozen film reviews. (See "Motion Pictures - Reviews.") Otherwise, I was searching blind, but managed to come up with a bunch of good stuff.
The next two days - eight hours each, from open to close - I spent at the Ohio Historical Society. For me, Ohio has been a somewhat problematic state from which to borrow materials, so I was really glad to be able to visit this midwest archival motherlode.
