What is the difference between a hardback and library binding?

1. Library binding is a little tougher

Up for rough handling by multiple people.

2. Library v. Hard back binding

Library binding usually refers to when a library takes a paperback and applies a hard back binding to it (or buys a book with the special hard(er) back binding). Generally, library binding is stronger than standard hard back binding.
