The 50 Greatest Books Ever
From https://thegreatestbooks.org/. This list is generated from 120 "best of" book lists from a variety of great sources. An algorithm is used to create a master list based on how many lists a particular book appears on. Some lists count more than others. I generally trust "best of all time" lists voted by authors and experts over user-generated lists.
