Nearly 600 medieval manuscripts from two German monasteries are now available to explore online, following the completion of a six-year digitisation project. The collections preserve texts ranging from theology and philosophy to law, medicine, history and classical literature.
The University Library of Erlangen-Nürnberg has completed a major project to digitise the surviving medieval manuscripts from the former monasteries of Heilsbronn and Sankt Jobst in Germany.

The two collections are particularly valuable because the libraries of Heilsbronn and Sankt Jobst are the only monastery libraries from the former Franconian margraviates of Brandenburg-Ansbach and Brandenburg-Bayreuth to have survived in almost complete form.
The medieval library of Heilsbronn

Founded in 1132, Heilsbronn was a Cistercian monastery in Franconia that developed into an important religious and intellectual centre. Its surviving manuscript collection reflects centuries of reading, writing and scholarship within the monastery.
The library contains biblical commentaries and liturgical works alongside writings by the Church Fathers, sermons and numerous texts associated with Bernard of Clairvaux. Other manuscripts deal with philosophy and Scholasticism, Aristotle, canon and secular law, grammar and rhetoric, history, saints’ lives, medicine and the natural sciences. Classical authors are also represented.

Sankt Jobst, a Franciscan monastery near Bayreuth, had a much smaller library. Its surviving medieval collection consists of 57 manuscripts, mostly written on paper. Their origins reveal connections extending beyond Franconia into Thuringia, Bohemia, Silesia and the wider Saxon Franciscan province.
The digitisation project was completed in three stages, with the final phase beginning in 2023 and concentrating primarily on paper manuscripts. Alongside producing high-resolution digital images, researchers updated catalogue descriptions and recorded information about the provenance of individual volumes.
Here are some of the manuscripts now available to explore:
Parabolae Salomonis – UER MS 8
Dating from the late twelfth century, UER MS 8 contains biblical texts and commentaries, including the Parabolae Salomonis, or Proverbs of Solomon. The manuscript is particularly notable for its unusual illustrations, including an allegorical image on fol. 130v showing paths leading towards heaven and hell.
Breviarii Partes singulae – UER MS 143
Dating from the 13th century, UER MS 143 is a breviary containing texts for Christian prayer and worship. Among its colourful illustrations is fol. 6v, which presents four scenes from the life of the Virgin Mary and the Nativity: the Annunciation, the Visitation, the birth of Christ, and the angel announcing Christ’s birth to the shepherds.
Thomas Aquinas’ Summa Theologiae – UER MS 266
Dating from the 13th century, UER MS 266 contains the Prima Secundae, or first part of the second part, of Thomas Aquinas’ Summa Theologiae. The manuscript features elaborate decoration, including an image of a seated scholar with an open book, surrounded by colourful borders inhabited by a chicken, rabbit and dog.
Biblia sacra – UER MS 439
Produced in Schwabach in 1450, UER MS 439 is a paper manuscript containing the second volume of a medieval Bible. One of its interesting features is this carefully organised table of biblical names, written in black and red and arranged in columns, showing how medieval readers created reference tools to navigate and study biblical texts.
Peter Lombard’s Sentences – UER MS 501
Dating from the 15th century, UER MS 501 contains Peter Lombard’s Four Books of Sentences, one of the most influential theological works of the Middle Ages, accompanied by extensive glosses. The manuscript features large decorative initials, while the numerous notes surrounding the main text reveal how scholars engaged with the work.

The University Library of Erlangen-Nürnberg has completed a major project to digitise the surviving medieval manuscripts from the former monasteries of Heilsbronn and Sankt Jobst in Germany.
Supported by the German Research Foundation (DFG), the six-year project concluded at the end of March 2026. It has made 531 medieval manuscripts from Heilsbronn available digitally, along with all 57 medieval manuscripts from Sankt Jobst, for a total of 588 manuscripts.
The two collections are particularly valuable because the libraries of Heilsbronn and Sankt Jobst are the only monastery libraries from the former Franconian margraviates of Brandenburg-Ansbach and Brandenburg-Bayreuth to have survived in almost complete form.
