Why not? I have been on this particular website quite a few times, but there have been other pages linked on here which I haven't been to so much. It's good to have a variety of interests. I am getting a broader range of websites and articles off here than mainstream media.
Are you looking for a yes/no answer, or for someone else to do the legwork for you?
I'll save you some time, the answer to you question is unequivocally: no. There are no other such archives for other religions or cultures. Just this one website.
Mileage may vary! The basic problem for an English speaker is that some languages are more translated than others. There are far more people translating from Greek, Hebrew and Latin works, than from Tibetan or Ge'ez (an Ethiopian language).
I've heard about the Taoist canon recently, which is seemingly vast, and despite Chinese being a major language, and a substantial number of people knowing both Chinese and English... Only a fraction of the Taoist canon is available in English.
There is a basic problem with some eastern texts, i.e. that many have not been translated into English. I was watching a video on Taoism recently, and a huge number of their scriptures are unavailable in English.
