Buddhist Studies: Texts of Buddhist Scriptures
This site is highly recommended, organised and well arranged for study courtesy of the Buddhist Education Association and Buddhanet. Very good resource site with translated material towards those who recognize English.
If perchance your referring to obtaining non-English works, inquire with the Buddhist Education Association in regards to the original Pali or Sanskrit. I would think they can direct you to the proper source.
As a side note, the app contains both variations oftentimes side by side in original language, followed with the English translation underneath in comparison.
