I have a good many aviation- related technical books, some of which are dated from the 1950s, and I frequently use them for reference purposes. My view is that you can never have too many sources of reference for subjects in which you are interested. But other people will of course have a different opinion.
The crux of this thread appears to be the suggestion that BGS stopped providing their books as an integral part of the course material, included in the course fees, and now offer them at an additional cost. Logically this process should have resulted in a reduction ln the course fees to compensate for the reduced materials provided. If there was no such reduction, and if there was no compensating increase in other course materials provided, then it was in effect a hidden price increase.
