To answer a couple of the requests:
1. Bertrand Russell's The History of Western Philosophy is available for free at the Internet Archive:
http://www.archive.org/details/weste...osoph035502mbp
(I can only assume that someone forgot to renew the US copyright.)
2. The MR library already has Dorothy L Sayers'
Clouds of Witness,
Strong Poison and
Whose Body, plus a couple of short stories featuring Lord Peter Wimsey.
I have managed to locate a copy of The Nine Tailors. It is out of copyright in Canada and life+50 years countries. I'm currently working on a conversion, but the file is full of scanning errors so I may need a few days. Watch the upload section!
