Bill Gates loves reading and he reads a lot. Below is his list of selected Best Books he had read in 2014. A number of them touch on economics and business and the library has them. =) If you follow his reading lists, Bill Gates’s reading genre is quite wide so I believe he would have a recommendation or two that will fit you.
