A special find has been made in the Alkmaar Regional Archive: A number of 17th-century book bindings contained pieces of parchment from a manuscript from the 11th century. The original manuscript may have belonged to a princess who fled England after the Norman Conquest.

Many books were printed and bound in the 16th and 17th centuries. Bookbinders used parchment to strengthen their book bindings; that material was expensive and therefore people often chose to cut up old, medieval manuscripts. This often involved manuscripts that had lost their value: books that were too Catholic or were written in a language that could no longer be read.

Something very special was found in a number of book bindings in the Alkmaar Regional Archive: 21 fragments of a manuscript from the 11th century, an almost 1,000-year-old Latin psalter with Old English glosses. Thijs Porck, senior university lecturer of medieval English in Leiden, was involved in the find and analyzed the text and provenance of the fragments.
