“Librarians love giving you free stuff, and you can often borrow way more kinds of things than you think. If you’re polite and the desk isn’t slammed, you can ask us damn near anything.

Even if we can’t find an answer, we’ll at the very least point you toward someone more likely to get you one. What we can do directly depends on the library (public or not, how well funded, specialized, etc), but we can get…creative. 

Also, interlibrary loans. If your library doesn’t have a specific book, we can usually get it from another library at little to no cost to the patron. Or, worldcat.org will tell you which libraries have what, if you want to go get it yourself.”
