Here is a sampling of web sites that offer non-English translations of Tipitaka texts. This is by no means an exhaustive list. Rather, I have selected a few representative sites that offer either a good selection of texts or a rich set of web-links to other sites in that language. Most of these sites offer texts (suttas, essays, etc.) that also appear (in English) on Access to Insight.
