It took the lucky convergence of the COVID-19 lockdown (with more time than one could ever have imagined) and watching the wonderful movie, The Man who Knew Infinity (as the inspiration) to reread parts of this unique reference book on Partitions. My focus was primarily on chapter 5 (The Hardy-Ramannjan-Rademcher Expansion of p(n)) and 7 (Identities of the Rodgers-Ramannjan Type). Like reading the score of a Bach fugue, I felt awe and no small degree of humility in navigating through the work of these great mathematicians.
Overall, the best reference book on the general topic I have found.
