Letterlocking: Historical Practices of Securing Information Workshop

Letterlocking: Historical Practices of Securing Information a workshop with Jana Dambrogio

Saturday, June 20th, 2015 9am to 4:30pm The Library Company of Philadelphia

What did Queen Elizabeth I, her spymaster Sir Walsingham, Marie Antoinette, and Russian WWII soldiers all have in common? They were letterlockers. They, and many others throughout history, folded and secured their letters without the use of an envelope. It’s part of a 10,000-year information security tradition, ranging from Mesopotamian clay bullae to Bitcoins.
Come spend some time with Jana Dambrogio to learn how they did it. If you identify yourself as an artist, conservator, bookbinder, archivist, origami maker, paper engineer, letter- writer, secret keeper, or information security expert, this is the course for you.

Jana Dambrogio is currently the Thomas F. Peterson (1957) Conservator at the Massachusetts Institute of Technology Libraries. She has been working in the preservation field for 15 years as a conservator, consultant, and teaching professional. She previously held positions at the US National Archives, the United Nations, and the Vatican Secret Archives. She is a Fellow of the American Academy in Rome and an active member of various book and manuscript communities. She teaches workshops internationally on how to look at, make models of, and develop approaches to conserving library and archival binding and letterlocking structures.

The Mysterious Voynich Manuscript: Collaboration Yields New Insights

 A talk by Paula Zyats, Assistant Chief Conservator, Special Collections, Yale University

The Voynich Manuscript, a mysterious vellum manuscript written in an unknown language, was donated to Yale University’s Beinecke Rare Book and Manuscript Library in 1969. In late 2008, an Austrian film crew approached the Beinecke with a proposal to conduct materials testing on the Voynich Manuscript and make a film about it.  This prompted an exciting collaboration between curators, scientists, conservators, historians, and filmmakers.  This talk summarizes those findings, outlining the history of the Voynich Manuscript, some of the theories as to its origins, conservation treatment, materials testing, and parchment radiocarbon dating. The advances though significant, are humble: the Voynich Manuscript’s authorship and meaning remain a complete mystery.

Paula has been in her present position as Assistant Chief Conservator for Special Collections at Yale University Libraries for the past 9 1/2 years.  In that time, she has been privileged to work on rare items from numerous special collections within the Libraries, including the Voynich Manuscript, and is currently working on a project to treat and house ancient papyrus fragments.

Jacob’s Ladder Structure

Denise Carbone

APRIL 5, 2014     10 am – 1pm

Library Company of Philadelphia

1314 Locust St., Philadelphia



The Jacob’s ladder is a folk toy consisting of blocks of wood held together by strings or ribbon. This 2,000-year-old Chinese toy has many wonderful applications for contemporary artist bookmakers. The book can be read straight through like any accordion book or hold one end and flip the ladder sections to reveal the hidden scenes. The apparent falling of the blocks has to do with a double-acting hinge. But to name it is not to comprehend it.

I will supply board for blocks, ribbon and polyethylene strapping for connector.

You should bring:

10 to 12 images cut to 3” square

Double-stick tape


Bone tool

(optional) your own ribbon
