The Post-Reformation Digital Library spans publicly-accessible collections from major research libraries, independent scholarly initiatives, and corporate documentation projects. With the increase of digital books scattered across various Internet sites, it can be difficult for scholars to find or keep track of all the new content. PRDL is a collaborative effort to organize this content for scholars of early modern theology.

The core of the PRDL project involves the collection of thousands of documents from select digital libraries from Europe and North America in their original languages (many non-English). The project covers the work of hundreds of authors from a wide variety of theological, philosophical, and ecclesiastical traditions.
