Do you buy physical books you have already read?
For example; I have read a book named “The Words We Keep” digitally. I loved it, it really resonated with me because it’s about something - I personally have and struggle with as well.
Thinking to buy the book physically but feel like, I can’t justify it due to the fact that I’ve already read it.
I don’t really re-read books either.
Sometimes, yeah, particularly if it was a copy I let someone borrow but they never returned for this or that reason, or if it was a book I initially read through the library and wanted my own copy (digital or physical) to review whenever.
As of late I’ve been reading more nonfiction though, where one may be more inclined to review them for learning/reference purposes.
