A good website for Mahayana texts? The classical canon gets good coverage with suttacentral and accesstoinsight, but I was wondering if there was such a website for Mahayana writings. (Post-canon writings diverge and become extensive, meaning different translators, copyrights etc, but if something relatively comprehensive-ish is around, would be great!)
I use Fodian.net a lot.

There are two categories of Mahayana texts, the ones that made it to China and the ones that made it to Tibet.

Within a specific sect or tradition, some sects have fantastic online documents, such as SGI's Nichiren library.

I'm less familiar with the Tibetan ones, but I do know that some of the Mahayana texts also made it to Tibet.

Scholars like Jan Nattier sometimes has to do comparison of the Sanskrit, Chinese and Tibetan to reconstruct a text.
