The problem with books is that:
a) they date very quickly
b) they rarely talk prices
c) it's the opinion of one person
When it comes to technique and how to use gear none of the above are big issues (just as long as you know that the writer knows what they're talking about) and there are some excellent books out there (like on the list Rokket posted).
When it comes to buying gear you won't get a lot of the info you need though, that's where this place comes in.
There is a wealth of info and an array of opinions here which can be confusing but if you familiarise yourself with the search facility and do plenty of reading you should get a good idea of what would be good for you.
If you're still unsure or if your circumstances are novel then you can ask questions in the appropriate forum.
(it's cheaper than books too
