The Center for Legislative Archives holds the records of the Joint Committee on the Investigation of the Pearl Harbor Attack; however, the exhibits were printed in parts 12 to 38 of the published transcripts. You can find public access on HathiTrust: https://catalog.hathitrust.org/Record/000596795
Congressional hearing transcripts can be located online or through subscription databases such as ProQuest Congressional. You can find access to ProQuest at most law and university libraries.
If you have any questions, I suggest contacting an archivist with the Center: email@example.com
