IMHO, I've created an interesting challenge in quite a roundabout way. Originally I developed this list for my personal use, basically as a reference list of recommendations and reminders. But looking at it objectively, I think many people should enjoy using it as a straightforward challenge.
The structure of the list is as follows:
01-08: Books recommended by our fellow list challengers (less one already completed)
09-16: Books that contain multiple shorter works and that I need to complete
17-88: Books to reach the maximum score on certain lists (aka my philistine collection)
89-96: Books recommended on podcasts and by others
As an example 'Don Quixote' and 'The Hottest Dishes of the Tartar Cuisine' are the 2 books I should read to complete the challenge, at the link, titled 'Books With the Biggest Morons in Literature'.
