Try requesting that your local libraries, both public and University, purchase books.
I've gotten my local libraries to purchase books by Tulku Thondup, Chogyal Namkhai Norbu Rinpoche, Lopon Tenzin Namdak Rinpoche, Longchen Rabjam, and many other books.
A University library card may cost money per-year if you're not a student though (I had a temporary job with the University, so my card was free, and it still works).
In the UK public libraries are being closed down due to lack of funding, but the University idea is good. In fact one local Uni offers a masters in Comparative Religion so I'll try them.
