My local library explained it to me once, but I don't remember all the details. I remember that it has something to do with controlling the inventory and not being required to figure out what to do with all the books they don't need. I do remember that the reason made a lot of sense to me. Maybe Mary Anne will weigh in on this.

It's not just libraries either. Most charities can operate a lot more effectively given cash to work with instead of only goods.

Most libraries will accept certain donations of some books or magazines, and many will cheerfully give you a list of what they are looking for.

Most of my old books end up at the used bookstore, where I now have a huge credit I don't know what to do with.

I hope their insurance comes through for them. Water damage is a tricky bit in homeowners insurance, I hope it isn't equally fussy for libraries.
