They may not be the very best books I have on my shelves, but they're my favourites. If you really want to know where I'm coming from as a reviewer, the answer is probably somewhere in there. And, to be perfectly honest, I'm not even so sure about all of the Great Works. I know that I read The Heart is a Lonely Hunter a while back, but I no longer have any recollection of what it was about. In terms of genre there is a definite hierarchy.
History is pretty near the top.
Hardcover fiction is hard to move, and you have to take a huge discount. Culture criticism and geopolitical analysis is demonstrably news that doesn't stay news. You couldn't give that stuff away at a poetry convention . If it's past its date the only thing you can do is throw it out. After two days of sorting I finally came to my old stash of comic books, many of them dating back to the 70s.
