As documented in the excellent book "Undocumented DOS", whose red cover I can still picture. (Noted in the article, but it was a good book that I still recall fondly.)
No. It's on the bookshelf next to Petzold, and below the other Petzold book, that I suspect far fewer have read, on the shelf above. On the other side of the Lower Petzold is Undocumented Windows.
If you deduced from this that the shelves were divided into Windows and OS/2, the sad truth is that the lower shelf is slightly too high, and the books are divided by height differences that amount to millimetres in some cases. Lower Petzold fits; Upper Petzold does not. (-:
