A large research heavy book and using Claude to help

I have a research heavy book I’m writing. 50+ interviews, averaging 5 hours an interview, 5,000 documents such as PDFs and screenshots of newspaper articles. I’ve given Claude access to my file structure and documents. I need Claude to help me parse and remember those documents so that I don’t miss something that might be pertinent to that chapter. Very smart crowd in this place, is there a prompt or something beyond me setting up a project folder inside Claude to assist with this? I can’t imagine every time I write about a subject or chapter, I ask Claude to read through each of my documents and pull relevant information, or say each time, go to interview A, now remember. Go to interview B. Ect. Thank you in advance, I pay for Pro if that even matters.
