Best Flimsy Textbooks (paperback books)

[newguy220]

Hello all, I was wondering what are some good textbooks that are flimsy (not hard cover and printed on cheap paper so lightweight) that can be read on the train and the bus easily (the dimensions doesn't matter to me, all that is required is for it to be flimsy). I need such textbooks for classical mechanics, electricity and magnetism, group theory, number theory and for analysis on R^N. I was wondering if anyone here has any recommendations for such textbooks or if you have any favorite flimsy textbooks of your own you would like to share. Thanks! :D

See https://www.physicsforums.com/threads/on-feynmans-qed.974784/#post-6207013 I'm presently reading Feynman's QED paperback, and it is very good reading.

Dover Publications has inexpensive paperbacks on most topics in physics. Take a look at their website.
