I have an old (1997) set of Trevor Thom books, so I thought I had better get some revised literature...
The Trevor Thom series are detailed and clear, with maybe too much information without drawing a fence around essential versus less important knowledge. My copies are black and white but I think the newer editions are colour ?
The Jeremy Pratt books are available for about 15quid each one of the set of 5 on amazon, but the Oxford aviation is 183quid for the set of 7. I haven't read either, so any comparative comments would be interesting. The larger format should be nice, but is it twin-columns of text ?
