I am a public librarian, and about half my working time is spent at the public information desk. Unless we're really busy, a good bit of that is spent just waiting for the phone to ring or someone to come up and ask a question. So here I am with an internet-connected terminal in front of me -- Mudcat definitely fills the void. I can easily switch to the catalog or whatever other site I need in order to answer a question, and switch back when I'm finished. I suppose I could explore wonderful new reference sites, and occasionally I do, but Mudcatting is better for my attitude...

Cheers, Nancy
