But check it out, it's one of those super informative sites that offers all sorts of free and interesting books, webcasts, downloads and related links to other super informative and FREE sites!
Truly, the Dharma is free, but these days it seems to me you have to pay for a great deal of it!
The Foundation is based in Taipei, Taiwan and does not "favour any one school or sect over another, and all are afforded equal respect."
Taking a quick look at the library of books they offer (yes, free), I would say this is true: there are volumes by Mahayana, Theravada and Vajrayana teachers. There are a couple of books for children and youth, as well as collections of sutras, sangha talks and even an English/Pali dictionary.
The downloads include Dharma talks and ebooks.
Really this is a treasure chest of free information!
Please check it out and have fun: www.budaedu.org
