Markd9528's 1-2-3 Book Challenge

I have slaved away to bring you this challenge, which could also be considered a handy reference list. Using "thegreatestbooks.org" and Goodreads websites, I have aimed to select a writer's most critically acclaimed and/or popular works. Generally, between 1 and 3 of an author's works were chosen for inclusion on the list, with the following methodology:1. Choose the authors' most highly-rated books, if any, from "thegreatestbooks.org" website, using both the fiction and non-fiction master lists, up to a maximum of 3 works (with the exception that up to 7 works could be included if they all were in the top 1000).2. If authors still had any of their 3 slots available, I chose their best rating works on Goodreads, using my judgement as to how many extras, if any, should be included.
