many of these i would definitely second
here are some that i think are good and have not been said yet (i think)
stars of magic (aaron fisher refers to this one alot)
beyond secret by jay sankey (book on theory)
some must haves i will second for sure are
expert card technique
paper engine
classics of larry jennings
bobo's modern coin magic
people are saying many different books but fyi i (in my opinion) do not think all of these books are "must reads" just choose wisely how you are going to spend your money
