Prior to 1980, some sources may appear authoritative and detailed, but seem to suffer from a lack of original research. A few are pretty reasonable. Read carefully and critically and be careful what you believe. A lot of new source documents have become available in the past 15 years or so, as archives catalog more of their collections. There's a lot more info than listed above. Additional articles on the subject are in the works.
