Thousands of parchments available online

Thinking it might be a useful source of inspiration, I'd like to highlight a collection of 3651 parchments made available online by the University and State Library of Saxony-Anhalt (ULB Halle), which purchased them in the late 19th century for paleography teaching purposes. These are parchments of Italian origin with dates from the 10th century to the 18th century.
