A colleague and I were searching for a copy of Evolution by Gene Duplication by Susumu Ohno, in part to insert some knowledge on the subject into my thick head, and Sweet Fancy Moses! it’s expensive. More than 2 Gs for a copy in good condition.  Given that it’s still the text on the subject I was shocked at how hard it is to come by.  Not even any e-versions I could find on Google.

There are copies (currently out) in the SFU and UBC libraries.  Any other options?
