Have yet to find a source to buy any of the actual books - any suggestions?
Here is another site to download an individual volume:http://www.buddhistelibrary.org/en/thum ... ?album=115
EDIT: This, from UCLA Buddhism Center, answers my question above:
Since the project was funded by a grant that only covered the publication of a limited number of paper copies of the texts, the texts are also being released in PDF format. A hard copy of the full set may be found in the UCLA Young Research Library.
