A collection of UAP related, and other documents by/about the late James E. McDonald has been uploaded to a server at Princeton University in the USA. The collection sits on the website of Kirk T. McDonald, Professor Emeritus, Department of Physics at Princeton.
Ann Druffel's 2003 book titled "Firestorm: Dr. James E. McDonald's Fight for UFO Science" gives details of McDonald's six children, including the eldest son Kirk.
The trove of documents, the largest online collection of James E. McDonald's work of which I am aware, includes copies of:
* Letters
* UAP magazine articles
* John Kenneth Gillin's 2013 thesis about McDonald's UAP work
* McDonald's statement to the 1968 UFO Symposium
* A 100 page PDF of summaries of audio recordings of McDonald's 1967 interviews of Australian witnesses
* Various talks by McDonald
* Meteorological papers
* Details of the University of Arizona McDonald special collection
* A bibliography
* Newspaper articles
* An MP4 file titled "Westall_UFO" re the 6 April 1966 Westall, Melbourne, Australia event.

I note that another one of McDonald's children, Ronilyn, in 1967 wrote a thesis as part of her Bachelors in Psychology titled "Psychological Aspects of Unidentified Flying Objects."
