"yaseer seirawan :winning chess strategies" is good book for rating 1300-1600. try this

A feature that many members are unaware of is that the forums are archived.  If you do a search of the forums ( the little box labeled "search forums" in the upper right) for "best book" or "best beginner book" you will find literally dozens of previous threads with lively discussions of books.  Kind of hard to recommend something without knowing a bit more of your strengths and weaknesses.

thx

Chernev's 'Logical Chess' would be suitable too

thx

"How to Think Ahead In Chess", by Fred Rienfeld and I.A. Horowitz

Very little chess notation of long variations.  Alot of words explaining the reasons behind the moves and openings they recommend.  Lots of diagrams.  You can read and study without getting out a board and pieces.

You can purchase it online for $0.79 in paperback plus S&H.
