One fewer frustrating book stamp

There’s nothing more frustrating to catalogers and bibliographers than a partially legible book inscription or stamp. While a completely smudged, faint, or illegible provenance marking might be disappointing it at least has an air of impossibility. Those that have some letters or words clearly rendered can suck hours of time. “So close! If only I could read those last few letters!” I’ve experienced this frustration too many times to count but the Penn Provenance Project has recently made the experience of finding a partial marking more exciting than exhausting.

A few weeks ago while reviewing the provenance records for all our codex manuscripts I came across one in a 16th century collection of Italian statutes that seemed tantalizing. The record read: “Illegible ex libris stamp: “Bibliotheca …”” Fortunately I could consult both the physical item and a new digital facsimile to try and reach my own conclusions.

I spent a few minutes squinting at the bottom part of the ink stamp, sure I could make out a dash and an ‘M’ but not really making much progress otherwise. I figured I’d head to the PPP site to try my luck. Though “Biblioteca” was sure to be dime a dozen on the stamps photographed in the project, it’s amazing how quickly one can scroll through a page of thumbnail images and so I got started:


Knowing that I was looking for an oval stamp with a hyphenated bottom word made a quick visual scan a cinch and in less than a minute I’d spotted the following mark:

I saved this to one side for comparison and moved through the rest without finding any other likely suspects. Going back to compare the two I was pretty satisfied I’d found the right one, the stamp of the Biblioteca Malvezzi-Medici in Bologna. The library of the counts of Malvezzi de’Medici was housed in their grand palazzo, one of the stars of Bologna until its sale in 1931. It turns out in fact that the Penn libraries hold at least twelve titles in print and manuscript bearing the Malvezzi-Medici stamp, acquired from the antiquarian market in the years after the sale.

Without the Penn Provenance Project and an easily searchable visual database of bookstamps I can’t imagine I would have found a match. Now the record for UPenn Ms. Codex 92 has been changed to reflect the new information and knowing the shared origin of this manuscript with other titles in the library will help us in the library as well as  scholars of Italian cultural and literary history better understand the collecting practices and historical imagination of Italian elites like the Malvezi de’Medicis. As we expand the PPP I can’t wait to hear many more similar stories of matches and surprising finds!

A Maddening Stamp

[This stamp has been solved!  It is the stamp of 20th-century Paris bookseller Arthur Lauria. Many thanks to Jasmin and Mitch Fraas for solving the mystery!]

Stamps should be easy to identify. You don’t have to decipher bad handwriting. You are more likely to find information about people, libraries or businesses who stamp their books since, presumably, they have collections large enough to make designing and purchasing a stamp worthwhile. [I say “presumably” because, as far as I know, nobody has ever wanted to find out who owned all of the Dell Yearling paperbacks proudly stamped “From the library of R.R.K.”] Of course, you expect a hefty challenge when stamps have only an owner’s coat of arms or initials, but when there is both a name and a place on the stamp, the mystery should be solvable. Right?


This Red Circular Stamp first appeared in Rare Book Cataloging a little over a year ago. It was smudged and blurry so I took a picture and crossed my fingers that the stamp would show up elsewhere in the collection.

It did. Several times.

And we still can’t read it.

We can say with confidence that the word on the bottom is “Paris.” On shakier ground, we speculate that the initial is an “A” and that perhaps, just maybe, the last name begins “Lab…”

It’s frustrating, and a little surprising, that every instance of this stamp in our collection is unreadable. I’m starting to wonder if the owner specifically asked that the stamp be designed this way or if the stamp maker routinely sold his stock at significant discount.
