It's funny how you cited sources and rather than be given information you were just told that you were very wrong without any attempt to distill knowledge.
For someone in the field, teaching is work, while telling people they are wrong isn't. Unless you are paying good money, you don't have a right to the former instead of the latter. In any event, the GP (note: not the same as the OP) could just look for himself on the shadow libraries, which now have pretty much everything.
I didn’t cite sources. You’re confusing me with someone else.
