I am not sure if this is the appropriate sub for this, but I thought there might be some folks here that could help me out:
I have been reading through some of the Church Committee documents, but I am having a difficult time finding the actual sources that are referenced in the footnotes. For example, in Book III there is a footnote: "Senior NSA official No. 1 testimony, 9/16/75, p. 47" but it really doesn't give any more reference or information about where this is being pulled from. I feel like I have searched thoroughly through the books and some have sections for evidence/exhibits/appendices/etc. but I am totally stuck and unable to find sources from Book III. Maybe someone here is a government historian or can otherwise help me out? Below is a link to Book III from the senate intelligence committee in case that's helpful.
