Could this to be the former door to Malmesbury's famous medieval library? No, it is not. It is a blocked up doorway on the south wall of Malmesbury Abbey. However, the door to this most prestigious ancient library would have been very close nearby. The library was part of the Benedictine monastery founded by Aldhelm around 676. William of Malmesbury (c.1090 -c.1143) was its best known librarian.
The library is gone now but some books still survive. Historians have always attempted to list the contents of the library and have wondered if Aldhelm's books would have been seen by William.
We do know the location of some of the surviving books. A list of 29 known surviving manuscripts from Malmesbury Abbey comes from a Bodleian Library Oxford project called Medieval Libraries of Great Britain. Six of these documents have already been digitised in their entirety and can be seen on the web. Here are some details of those six.

A history of the world written by a monk of Malmesbury in the 1360s. It is a vital source for the history of Malmesbury and contains an eyewitness account of the Black Death.

A late Anglo-Saxon text is illustrated with beautiful line drawings. It contains a curse threatening damnation to anyone who removes the book from Aldhelm’s library at Malmesbury. The curse is the only proof that this book was in the Malmesbury Library.

This 11th century copy of the work of Gregory the Great was produced on the continent. It contains notes by William of Malmesbury and there is a good chance that it was obtaimed for the abbey by William himself. A later monk has inscribed the manuscript: Iste liber est de monasterio Malmesburye et in custodia ffratris Thome, that is, This book is from the monastery of Malmesbury and is in the care of Brother Thomas.

This 14th century document contains the monastic psalms, a calendar of feasts and the Litany of All Saints. It clearly comes from Malmesbury because Aldhelm gets pride of place in both the list of feasts and the litany. At some point it was obtained by the great Swiss Benedictine monastery of St Gallen.
