I contributed a chapter to the book The new Academic Librarian edited by Rebeca Peacock and Jill Wurm. This is a link to the chapter I wrote found on Google Books.
I’m really forgetful. I think that’s one of the reasons I’m a librarian. I imagine that information is easily accessible enough that I can just look it up anywhere. Today I forgot my office phone number! Anyway, after searching for myself and my office phone number, I came across this chapter.
I think it’s a little dated by now, but probably gives a good idea of what a typical web librarian does.
