Why libraries?

I've had people ask why I include libraries in my travel guide. Libraries are a great travel resource for multiple reasons. They often have wifi. Sometimes, you can even access the wifi from outside when the library is closed. And, of course, they have public restrooms. They often sell used books, so travelers who don't want to bring books (and haven't packed a kindle or ipad with electronic books), can refill along the way. Finally, if you want information about the town, libraries are a good place to go for questions, either to the librarian or to the local books on site.
