I've said it before, and I'll say it again. If something is at PG and not here, then the best way to get it here is to "do it yourself". It's really NOT difficult - I've written tutorials explaining one way of doing it (there are many others)
here and
here.
Most of the books here have been uploaded by a small number of people - it would be great to expand the number of contributors to our book collection. Please do "have a go"!
