George W. Bush Library

Texas has more presidential libraries than any other state. And they’re going through changes with regard to accessing classified documents.

On the 10th floor of the Lyndon B. Johnson Presidential Library in Austin, the sound of archivists pushing wooden book trucks on the bright red carpet is a familiar one.

"We have a reading room where researches come to do the research, and we bring up the boxes that they need," Senior Archivist Regina Greenwall says. She's the team leader of the library's foreign policy staff. "And they work on them in the reading room under supervision. The stacks are where we keep things not in use or that have not already gone through the process of being opened."
