I just got Fa-Hsien's 'A Record of Buddhist Kingdoms" which is free in Kindle form.
There is also a lot of junk there but many valuable texts - several by HHDL, Lama Zopa, Thubten Chodron, Ani Palmo, Lopez, the study of Gedun Chopel, Andreas Doctor's study of terma text's, one of Bhikkhu Bodhi's sutta collections - Jigme Linpa's Deity, Mantra, Meditation - The Three Visions (Sakya Lamrim text) - Zurchungpa's Testament! - Naked Awareness! - Khenchen Palden Sherab!
I could dance!
The dream of creating a mobile elibrary that has been slowly happening since before the Web is now really becoming reality!
There is in fact much more available than I had imagined. Amazon's search results are poor when searching for Buddhist texts - they do apparently use an ontology to help guide their search but it is not tuned correctly for a practitioner (or even a secular scholar). Most of Geshe Sonam Rinchen's works are there for example but didn't apparently come up when I searched just using buddhism or tibetan buddhism as search terms.
HE Jamgon Kongtrul's Treasury of Knowledge - just overwhelmed ....
