Of course books can help you improve your skills. Some books for beginners:
Garry Kasparov's Checkmate! My First Chess Course is perhaps intended for teenagers who are learning the game for the first time. It has tons of full colour pictures and diagrams, and is very easy to follow. He offers a few tips, but you probably need other books to flesh out what he says.
Learn Chess with Nigel Short is another good first book with lots of diagrams. Short shares interesting little tidbits about his travels as a chess player.
Patrick Wolff's The Complete Idiot's Guide to Chess is a lot longer and more involved, but also uses a lot of diagrams, and is easy to follow. He gives some good tips on strategy.
Is the books are helpful if yes then which book is best to be a advanced chess player....
