A note on language:
Early works in Jainism were primarily written in Prakrit (dead vernacular languages of ancient and medieval India) as opposed to classical Sanskrit (used primarily by aristocracy and priests)
When looking for resources in Jain Studies searching the title of the work in Prakrit or, for later works, Sanskrit is especially useful.
Below are some useful resources for the study of Prakrit
The question of "sacred texts" and "canon" is always a complex one in religious studies and Jainism proves no different. It is beyond the scope of this guide to provide a complete list of Jain canonical literature--especially as the "canon" differs substantially between the Svetambara and Digambara sects (the two main sects of Jainism). However, listed are useful resources for locating the different "canons".
