I also spent a few hours assessing my research strategy. I have been doing inter-library loans for five years. The first ILL was submitted November 1, 2001. I know because I have a 48-page log detailing what I've requested, what I've received, and where it came from. I must have submitted hundreds of requests, and only a few times have I mistakenly requested material I've already looked at. I have amassed a ton of material. Some of that material will soon see the light of day. I promise.
While assessing my research strategy, I mapped out what I have left to do. There are still many more requests to be made - the bulk of which come from Pennslyvannia, New York, Kansas, Canada and a clump of "elsewhere." The search goes on.
