Organizational History of the CIA, 1950-1953

Quick post about a document that might be of interest to my fellow researchers. In the course research for an article, I came across the chapters for a CIA internal history titled “Organizational History of the CIA, 1950-1953“. From the Chapter X PDF file, we can learn that this history is part of the DCI Historical Series, issued in two copies in 1957.

As is the case with some other titles, this history is only available as separate chapters released at separate times. I am consolidating below what is available, and submitted a FOIA request for the missing chapters. (Update Feb 2022: I received Chapters VI-VII from the CIA!) Of the annexes, only A and B are available in the online archive.

For whatever reason, the Chapter X PDF files had all the pages out of order. I rearranged the pages so that they’re in the correct sequence now, and I’ve made the fixed (and OCR’d) file available through Google Drive.

Multiple versions are available of some chapters, which seem to be different physical copies. On some of the documents markings “2nd carbon” and “3rd carbon” can be seen at the top of the front page.

Below are all the related PDFs which I have so far been able to locate in the archive:
