Just as every Tibetanist has her or his idea about how to transcribe Tibetan script into the Roman — the very word 'Romanization' strikes fear into many, and rightly so — every one of them has different ideas about the history of the Bon religion. I won't venture to guess which position you are taking. Well, Are you a believer in Bon as the truly original religion of Tibet? Do you think it came from a place off to the west of the Tibetan plateau called Tazik? Do you think it's just another form of Buddhism adapted — whether through natural processes or intelligent design — to the Tibetan culture and mentality? Whichever slope of this three-sided pyramid you may be falling down at the moment, you will find something to edify and entertain you in the literature about Bon and its followers, who are called Bonpos.
So without too much more ado I will just send you to our sister site where I've just successfully uploaded a new combined bibliography of Bon. It ought to be entirely annotated, but as it turns out only some of the entries have accompanying descriptions.
I think it would be safe to say that this is the biggest bibliography of literature about Bon of its kind. It is true that there are bigger bibliographies of Bon literature in Tibetan language, including catalogs of the Bon Ka and Katen — popularly misnamed the “Bonpo Kanjur and Tanjur” — and a very big bibliography of Tibetan-language reprints done by Samten Karmay. You'll find those bibliographies listed in this one.
PS: I'll be going off now in an attempt to hang up a PDF version of the thing, since it looks a royal mess the way it is.
Well, that was a lot easier than I expected. Done already. Bon nuit, mon ami.
