This is a question for librarians. Is it OK to return materials a few days (or even the next day) after borrowing? I'm a fast reader and watch movies quickly or sometimes just know I won't enjoy a book after a few pages. Is it annoying or bothersome to return them way before the due date?
Why would it be?
For one thing, if it is a really popular boook with a lot of reserves, that is great!
Yes! As a school librarian, I did sometimes ask. "Did you get into it and not finish it?", "Did you love it and read it quick like a bunny?". merely because I wanted to tell the other students.
As a public librarian, it is none of my business unless the borrower wants to tell me something.
Anyway, most returns are anonymous.
