learning

Actually according to the Chess.com rules, it is OK to use books during a game:

You may NOT get any help from any person or any chess engine that analyzes your specific position, including tablebases. You MAY use books, magazines, or other articles. You may also use computer databases. EXCEPTION: If both players agree for the use of a chess engine in an UNRATED game then it can be allowed.



What you're doing: using books to get better is completely alright, and its very silly of your opponent to do that. However, using "books" "during" a game is a more touchy subject; while it is cheating in OTB chess, I cannot say what the verdict is for Correspondence Chess.
edit: There seem to be some people who do not understand your query. You're talking of using chess book when not playing a game, yes?

Yes, thats perfectly fine. Don't let anyone tell you otherwise.
If two people were playing a sport, and one didn't like playing the other because he "practices" then, well, to me that just seems dumb and it would go the same for your situation.

Would you say,reading a chess book, learning from it,puttiing it into pratice in a game,cheating, I ask this because I have done this and now a member of chess.com will not play me now as they would rather play a more natural player. Im not using the book during the game.
