 So it's all here, the story of our time with the barcode. There is no record of a mistake or an unpleasantness or criticism that is not included in the files here. This library will show the facts, not just the joy and the triumphs, but the sorrows and the failures too. We're eager to show you the magnificent building that we have the pleasure of working in every day. The building was designed by Gordon Bunshaft, who was chosen by President and Mrs. Johnson in the late 1960s. There are many stunning and unique features of our building, but the most notable is the Great Hall. If these walls could talk, they would share stories of history. President and Lady Bird laying in repose, many presidents, both current and former, gracing these stairs and exhibits, and the millions of school children and visitors who have stepped foot in the Great Hall to gain a greater appreciation of President Johnson and the tumultuous era in which he lived. This is my colleague Ruth Gerger. Ruth is the Associate Curator of the LBJ Presidential Library and knows as much about the Great Hall as anybody. Ruth is going to lead you on a tour of this historic space. Ruth? Thank you, Mark. It's the details and grandness of the Great Hall that really make it unique. From the travertine walls to the engraved presidential seal and the spectacular view of the archives collection, the Great Hall really lives up to its name. Most visitors begin their ascent into the Great Hall via the ceremonial staircase, where they are met with an obelisk engraved with quotations. As you reach the top of the stairs, your eyes can't help but move to the display of the archives collections. The LBJ Library has a unique feature in that we display our archives so that our visitors are aware of why this institution exists. Lady Bird Johnson visited all the libraries that existed when President Johnson took office and made note that visitors and researchers entered through different doors, a feature she did not want to be true of the LBJ Library. Additionally, four stories of archival boxes are on display behind glass, which was inspired by the Beinecke Rare Book and Manuscript Library. The LBJ Library underwent a major redesign in 2012, leading to some changes in the Great Hall, as you can see in this time-lapse video. The architect Gordon Bonshaft wanted to make sure the integrity of the Great Hall remained for years to come. That's why it's made from stone, like the outside of the building. In an oral history conducted in 1969, prior to the dedication of the library, Bonshaft said, we want to make sure that the bad taste of various people won't affect the building. The Great Hall itself is 7,686 square feet, the equivalent of 6.6 Olympic-sized swimming pools. This multi-purpose space, first and foremost, allows for permanent and temporary exhibits. The presidents and the first ladies, as well as the Legacy Gallery, were updated and created as part of the most recent redesign. There are two small cases that hold temporary exhibits, such as George Washington's annotated Acts of Congress, the cornerstones of civil rights, and other fun highlights from the LBJ Library exhibits. The space also holds many visitors during open houses like Explore UT, exhibit openings, evening receptions, and more. In addition to these unique events, the Great Hall has spectacular acoustics, which are taken advantage of by university and school choral groups that stop by throughout the year. Thank you for visiting the LBJ Presidential Library's Great Hall. We hope you enjoyed this video as much as we enjoyed making it.
