 Yeah, so, well, I'm a historian, so I like to read other people's mail, especially when they're not alive anymore. So the records I used that were not usually used for this kind of study were the documents of the legal cases and the documents of the National Labor Relations Board. And are they public? They're public. You can get them. They're not published. They're in the National Archives in College Park, outside Washington, D.C., College Park, Maryland. Paste files, thousands and thousands of pages. So legal briefs, transcripts.
