A friend of mine forwarded me this - someone posted to a message board asking if anyone knew of a book rental service.
The idea of someone not knowing what a library does echoes a recent discussion on MELIBS-L - one Maine librarian shared this story:
I just had a nanny who has recently started bringing a little boy to story time come into the children's library and see me sitting at the children's reference desk. She said, "Oh, you work here, too?" I looked at her, puzzled, and she said, "You don't just come in for the children's programs?" I explained to her that I am the children's librarian and that I work full-time. She said, "Oh, what a cute little job!"
This led to a discussion about how the public sees libraries, and how we need to do a good (better?) job of marketing ourselves.
