Keeping it Cool – Designing the Library’s New Gutenberg Bible Display Case

Monday, April 27th, 11am – 12pm Register here

The Library of Congress’ Gutenberg Bible is on permanent display in the Thomas Jefferson Building. Even though its three volumes are displayed on a rotating basis, the concerns about the adverse effects of long-term display required the Library’s’ conservation staff to create a purpose designed display case that would mitigate these adverse effects. The speakers will talk about the design process, present various features of the new case, and share with the audience some lessons learned now that the case is fully functioning for a little over a year.

Presented by Elmer Eusman, Chief, Conservation Division and Nancy Lev-Alexander, Head, Collection Stabilization Section

Acquiring and Developing an Offsite High Density Collections Storage Facility

Tuesday, April 28th, 11am – 12pm Register here

In addition to operating state-of-the art preservation quality storage facilities at Ft. Meade, the Library operates a rental property which meets its needs for interim storage.  This webinar discusses the Library’s experience in acquiring and developing this facility.  Cabin Branch (located in Landover, MD) shows a way to control costs without compromising on collections care.  The webinar will explain how the Library of Congress designed an interim storage warehouse with collections safety foremost in mind, while keeping cost under control by working with the developer to focus on the features most critical to safeguarding our collections.

Assessing the Condition of the United States National Collection

Wednesday, April 29th, 11am – 12pm Register here

A national research initiative funded by the Mellon Foundation “Assessing the Physical Condition of the National Collection” is undertaking the task to objectively assess the condition of books held in collecting institutions of the United States by performing an in-depth scientific analysis on a representative sample.

The research focuses on analyzing the same 500 volumes from five different research libraries in five different climatic zones through the time period 1840-1940. Research to date has shown some extremely interesting trends. This presentation will focus on the analytical techniques used in the program and show what this means to the preservation of print collections throughout the United States.

Presented by Fenella France, Chief, Preservation Research and Testing Division

Environment, Housing & Building Materials Testing to Protect our Collections

Thursday, April 30th, 11am – 12pm Register here

Challenges to preserving the national collection come from both inherent risks in the collections themselves and from materials in the immediate environment. The Library’s quality assurance program is focused on analyzing all materials that come into contact with collections or are part of the surrounding environment. The quality assurance (QA) program involves testing of materials used for housing, storage, and in conservation treatments, as well as evaluation, definition, and dissemination of standards for the use of these materials.

 This presentation will give specific examples of QA testing, new developments in quantification and identification of volatile organic compounds, fast and accurate test methodologies, examples of collection inherent material challenges, and assessment of off-gassing from potential building and housing materials to determine safety for special collections.

Presented by Dr. Eric Monroe, Supervisory Physical Scientist

Would You Like to Save Your Game?

Friday, May 1st, 11am – 12pm Register here

Libraries, archives and museums are facing an ever increasing amount of interactive media in their collections, including software applications, time based artworks and video games. These materials provide unique challenges in regards to acquisition, description and preservation, and many institutions are working to develop new approaches to ensuring the long term preservation of and access to born digital cultural artifacts. The Library’s National Audio-Visual Conservation Center (NAVCC) holds over 5,000 videogames amassed through copyright deposit and private donation. This collection contains not only a wide array of formats from 5.25” floppy disks to modern console cartridges, but also packaging, documentation, and adjacent materials such as magazines. The Preservation Reformatting Division and NAVCC work together to describe, reformat, and preserve these complex digital objects and preserve this important part of culture. This webinar will highlight different aspects of the preservation workflow.

The Library of Congress Turns 220

In 1800, as part of an act of Congress providing for the removal of the new national government from Philadelphia to Washington, President John Adams approved an act of Congress providing $5,000 for books for the use of Congress—the beginning of the Library of Congress.

Since that beginning 220 years ago, the Library has grown to become the largest library in the world with a collection of more than 170 million items that document human creativity and achievement across the centuries and around the globe.

Collecting and providing access to these collections takes on a new meaning and significance in our current world. With social distancing as the norm, and more time spent at home, we want to continue to highlight ways to connect with our content, our knowledgeable staff, and each other during these times. From April 24 to 30, you can celebrate the Library’s 220th birthday by participating in online programs from across the Library, reading themed posts on our blogs and social media channels, and downloading our brand new app to explore the Library’s digital collections from home.

The Library of Congress buildings remain closed to the public, with all public events currently canceled through July 1. Visit our web site for full, up-to-date information about our response to COVID-19. In the meantime, we invite you to our virtual birthday celebration and to continue to engage with us through some of the resources listed below. We look forward to continuing to serve you during this season and beyond.

Sincerely,
Carla Hayden, Librarian of Congress
