First off, did you know you can buy books from chess.com? Go the "more" button at the bottom of the left tool bar of chess.com and go to shop for chess supplies. You can buy a lot of stuff there. Chess.com is now a one stop shop. It isn't like it was way back when us cavemen where playing chess...
Anyway, as a beginner, one probably doesn't have the necessary board vision to go over a chess book. Yeah, they can with two boards, one for the current position, and one for sidelines to experiment with, but even that, takes a lot of prior knowledge. You almost have to start from online stuff. What was mentioned by other people, do that, especially what the Keto guy said, I can't spell his name...
Anyway, as a beginner, one doesn't have the necessary skill to come up with their own lines after a computer analysis. Let me put it to you this way. I'm 1500, and I still don't use the computer for the most part...Silman said something about the computer, he said, turn it off. This is a very knowledge chess coach, so listen to his wisdom. Shut off the computer analysis.
With guidance, one can possibly learn from a chess book at first. But, in order to do that one needs a coach to pick out the books. You can't do it on your own, nor can you let subpar players tell you what worked for them and tell you to do the same thing. If you want free, don't expect much. Nothing in this life is free, and neither is a chess education. If you want free, play checkers, or if you don't want to devote hours to private study to learn perfect checkers than play tic tac toe. But chess, takes skill. You need to learn from the best, or someone better than you, to succeed. You need to make chess friends, preferable strong players, and play them occasionally. You can start with your local chess club. Good luck.
Chess, like anything else, is a time + effort, investment. If you aren't interested enough in it then find another game, because one can't get good at chess if they don't actually like it. I know a friend who was forced to play chess by his father, he hated it, but this guy went on to succeed in life and teach his son calculus, in a much more gentler way, as his son was already interested in the subject, as he is a genius.
Chess requires a lot of time. If you don't have the time, then chess is not for you. I'm sorry to say this, but I'm telling you for your benefit, so you don't waste your time on a game that you "can't" get better at. Again, good luck with your chess.
