Around 2010, as an undergraduate in mathematics I fell absolutely in love with the Riemann hypothesis (RH), as one does. I spent Friday nights researching, reading and trying to understand this most famous of all math problems. In the process, I accrued a bundle of books on the topic. Some were better than others. The following are the ones I would recommend to another 21-year old interested in understanding the Riemann zeta function, its properties and the implications of Riemann’s hypothesis for the distribution of prime numbers.
