"Authenticity"
Rare Book and Special Collections Division
The Library of Congress
December 6, 2013

The Library of Congress announces a  symposium on “Authenticity,” a program that will look at one of the most difficult subjects facing libraries, private collectors, and booksellers today—judging the genuineness of printed materials.  The symposium will not focus on theft or forgery, but rather on the research which curators, scholars, and conservators have been conducting regarding all elements of printing and book production.  The program will include specialists who are at the cutting edge of research on printing techniques, paper manufacture, binding construction, and typography.  They will include scholars, conservators, scientists, and booksellers who are dedicated to establishing methods for determining authenticity in the field of rare books, prints, and manuscripts.

The symposium will occupy the entire day and will close with a keynote address by Michael Suarez (Director, Rare Book School, University of Virginia).

The Program Schedule:

Panel on Paper
Tim Barret (University of Iowa), Kim Schenck (National Gallery of Art), Peter Bower (Forensic Paper Historian, London)

Panel on Printing and Typography
Paul Needham (Scheide Librarian, Princeton University), Nick Wilding (Georgia State University)

Panel on Color
Thomas Primeau (Baltimore Museum of Art), Meg Ford (Christies London), Lynn Brostoff (The Library of Congress)

The one-day program will be held on Friday, December 6th, 2013 in the Mumford Room of the Library of Congress' Madison Building.  The program is free and open to the public, but seating is limited.  An RSVP would be appreciated. Please contact Geanie Jackson in the Rare Book and Special Collections Division at gjackson@loc.gov or 202 707 6253 to confirm your attendance.
