Herbert,
there are lots of second/third hand books for cheap at the famous auction site available. You know that one, I am sure [but TradGang would disable the word if I type it in here - use your imagination - ending on 'Bay'].
Some general advise for you:
Go for books published in the 1960th or early 1970th - this is - BEFORE the Compound boom. They will cover all you need and not devote 3/4 of the book to unneccessary wheel bow tunig and gadgets.
Just yesterday I pulled one out of my shelf to look for something special and was again pleased with it's content. No problem to recommend it to you:
Jack LEWIS (Ed.) Archer's Digest (1971), 320 p.
This is a big paperback with typical lousy paper quality, but images are all nice. Lot's of bowhunting advise in there too. There are many others in this kind of books and they offer a broad pallet for almost no money.
I never hesitate to recommend one very good book, which deserves far more recognition then it obviously gets:
SCHUYLER, K.C. (1970): Archery, From Golds to Big Game. – 569 p., >250 figs.; New York (Castle Books).
As the title suggests, it will cover every aspect and is good reading. I like it alot - and I do have above 100 different books on the subject to compare! Every now and then it's available at the auction site too.
From the above mentioned I'll second T.J.Conrads work as one of the best books published during the last years.
I don't think Byron Ferguson's Become the Arrow will be one your should looking for - at least not now. It's almost exclusively focused on shooting technics and form.
Fred Bear's Archers Bible (1968,1980) covers a lot of ground ...
It all depends on what your main interest is - I could go on and on ... sorry for the lenghty reply!
