I've only had the chance thus far to scan quickly through the volumes to size up the content. However, I did spend time reading an article in the third volume that caught my eye on Military Academies. In an otherwise well-written and entertaining article, there were a few instances where serious, likely OCR-related goofs appeared in the text, e.g. "2136" instead of the proper "2D6" and places where "D" was misinterpreted as "Q"! Open parentheses were either deleted or misinterpreted, and two or three places where there must have been hyphens (-) were omitted, making references to negative DMs look odd. With a modicum of head-scratching I was able to get around these idiosyncracies, but I sincerely hope that the remainder of those three volumes do not bristle with such egregious OCR problems.
EDIT: To provide an example....
Issue #26, p. 25:
AS=(2xEDU)+QxINT)+SOC
Now, is that supposed to be (DxINT) or (2xINT)? I'm inclined to think the latter, but elsewhere Q is the result of misread "D".
