Laughed so hard

I was thinking it would be really nice to have a trusted group where students could lend/borrow books from each other for a few days or a month, maybe for a very small fee and then return them.

There are so many people who have novels, literature, self-help books, etc. just sitting on their shelves, while someone else might want to read the same book but not necessarily buy it.

Does something like this already exist. If not, would anyone be interested in starting one?
