I agree with the "any company BUT yours".
I think those who get that far are into personal one on one teaching, or have progressed beyond the "wiccan" and "pagan" books and are studying other things of depth - lke comparative religions, mythology, herbology, etc.
Personally, I find almost all of the Llewellyn Press books only good for propping up table legs, and to use whent he power goes out to keep warm. But then, I find better things to do with my money thsn buy their books - like buy cotton candy. Same worth, same value, same longevity.
