Do you reread books or are you done with them once you’ve read them?
I like to reread books sometimes! Rereading is especially good if I’ve just finished something heavy or intense; I can follow that up with something that I’ve enjoyed before so it doesn’t take too much effort and I can have a bit of a break. I also don’t have the greatest retention for what I read, so even if I’ve read something before there’s no way I’ll remember everything. And there are certain books that are comforting and cozy and those are great to reread when I want that kind of mood.
I re-read books frequently. But then, I am a fast and voracious reader. I've recently been trimming down my library from around 7000 books due to an upcoming move, and there's a hardcore of about 2000 I'm unwilling to get rid of because they're either reference materials or old friends I expect to re-read before I die. There are some things (LOTR, much Heinlein, Oz books, Alice in Wonderland...) that I've read a dozen times or more.
I do re-read some non-fiction, mainly history. But most of my well-worn books are fiction.
