Discussion: What Do You Do With Your Books When You're Finished Reading Them?

If you're active in the bookish community, you'll see that there was a Youtuber that stated that you should only have like 30 books in your home. I haven't seen that video, nor do I plan to. I've noticed that it's been quite controversial and not many people are happy with what she's said.

I don't know if it's like a minimalist thing or what. I'm just really curious to what you guys think about this.

Personally, I keep all of the books that I spend my hard earned money on. Unless I really disliked the book. Or if I know I'll never read it. I like to display all the books I own. It makes me proud.

What do you guys do with your books when you're done reading them?
