The Library of Congress holds the largest group of Whitman-related special collection materials in the world, including printed materials, rare books, photographs, and manuscripts. In this webinar program, Manuscript Division historian Barbara Bair highlights the content and research use of three digitized Whitman manuscript collections as well as programs celebrating Whitman’s birthday at the Library of Congress.

Date: Thursday, May 30
Time
: 1:00 pm – 2:00 pm EDT
Registration (required): Please register via Eventbrite.

This program will be held in real time via webinar software, which allows participants from around the country and the world to join us. Confirmation and log-on instructions will be sent via email. Please read the Library of Congress Comment and Posting Policy.
