I see that there is "The Martian Chronicles" by Ray Bradbury (33 mentions), and "The Martian" by Andy Weir listed much later (11 mentions), but most of mentions for "The Martian Chronicles" appears to be referencing "The Martian" instead.

Also, "Gödel, Escher, Bach" (20 mentions) and "GEB" (7 mentions) are listed as separate books, but they are the same book.
