what do you do with your old editions when you buy the newer edition?

give em away, preferably to people who will read and appreciate them. alternatively, sell them at your local used book store (provided that's an option).

I donate them to an English teacher I know so he can provide his advanced students with challenging reading materials.
Sometimes I contribute to my local little free libraries as well so they're not just filled with trashy romance novels thrown away by housewives.

i give them away as birthday gifts to people i know will read them at some point.
if i don’t have a duplicate, i keep the book. You shouldn’t sell or throw away books, unless you’re really poor or running out of space in your home.

I don't buy books. I just use the library.
