IF YOU’VE EVER BEEN EMPLOYED as a generalist, I salute you. Working at the reference desk of a public or academic library is tough. You just never know what topic will arise. And somehow, you’re supposed to know everything about everything, ranging from anthropology to zoology, with current news events thrown into the mix. We’re all familiar with the librarian motto that we don’t actually need to know everything, we just need to know where to find it.
