I sent stacks of paperbacks to the charity shop when I first got my Kindle. Then some years down the line, I decided to do my Master's (in literature) followed by my PhD (ditto) so now I'm up to my ears in physical books again. You can't get everything you want in ebook editions and physical books are better/easier for referencing. Plus the idea of doing high level research in literature without using actual books was miserable. On the other hand, I've got musculoskeletal problems and I try to keep down the size and weight of my bag. You can't beat an ereader for helping with that and my Kindle is always busy.
So I've got multiple (especially ebook and paper) editions of books by F. Scott Fitzgerald, Jane Austen, Charlotte Bronte, Emily Bronte, Wilkie Collins, Patrick Hamilton, Edith Wharton, Henry James, Daphne du Maurier, George Eliot, E. Nesbit, May Sinclair, Elizabeth Bowen, Charles Dickens and probably a lot more if I think about it.
