The Edition Open Sources is dormant

In 2013, an agreement between the Max Planck Institute for the History of Science and the University of Oklahoma Library, both of which conserve large rare book collections, led to the launch of Edition Open Sources, a relaunch of the Sources series of the original Edition Open Access platform.

The series typically presents a primary source—relevant for the history and development of knowledge—in facsimile, transcription, or translation. The original sources are complemented by an introduction and by commentaries reflecting original scholarly work. The sources reproduced in this series may be rare books, manuscripts, documents or data that are not readily accessible in libraries and archives.

Notable in this series, among others, is Pseudo-Proklos’ Sphaera: Die Sphaera-Gattung im 16. Jahrhundert by Johanna Biank. This edition investigates the reception and transformation of a classical cosmological text—falsely attributed to Proclus—within the Renaissance tradition of astronomical teaching. Drawing on a rich corpus of manuscript and print commentaries, Biank reconstructs the diverse ways in which early modern scholars engaged with the Sphaera genre, offering new insights into the intellectual networks, didactic practices, and cultural contexts that shaped its dissemination. The volume combines rigorous source criticism with digital facsimiles, making it a model for philologically grounded and historically embedded editions.
