Confessions: I keep dumping Ulysses and have only ever read it in parts. I've cheerfully dumped The Alchemist. I skipped a lot of pages in the Sloosha's Crossing section of some sections of Cloud Atlas. (Loved the book as a whole though.)
I can understand why Captain Corelli's Mandolin makes the list. It's one of my favourite books of all time (as I keep telling the world - I've never laughed and cried so much when reading a book and took to my bed for a couple of days in a state of total emotional collapse!) but when I've given it as a gift to less convinced readers I've advised them to skip a couple of chapters at the beginning if they get stuck, and come back to them later. One of the criticisms I have of the novel (a teensy one compared to the fact that my beloved Corelli disappears for decades) is that the first part is not terribly well structured.
Another of my favourite books of all time is a dumpee on this list - Crime and Punishment. (The Visitor will be rubbing his hands in glee!)
I guess some people dump Vernon God Little because the language offends or maybe they don't appreciate Mr. Dirty-But-Clean Pierre's pyrotechnics. Again, one I very much enjoyed.
A point I've made before: there is no shame in dumping books you aren't enjoying. Do it guiltlessly.
But some books, it has to be said, do take a bit more effort to get into ...
