Great question, Betha.
Similar story: I was waiting for the bus just this last week and another person waiting told me, in passing, that they had just recently moved to Seattle and had lost their identification. Not knowing much about the process of getting new identification without other documentation, I said "Have you tried the library?" He looked at me, stunned, maybe confused. I explained, "You can go to the library and the librarian will help you figure out what you need to do to get new ID. They can prob even give you information on getting a copy of your birth certificate." He said, "librarians can do that?" I said - "Yep, and it's free."
Whether I'm talking to a friend who *knows* I'm an information specialist, or strangers waiting for the bus - the answer I give to almost any information inquiry is "Go to the library _________ (insert Web site, reference desk, history desk, etc.) and you'll get to it, or someone will help you get to it."
Now, how to capture how truly amazing that is - the last organized bastion of democracy and all that - in one sentence, well...
"@ your library" does a pretty good job (in terms of marketing these concepts.
In conversation, I think that it's effective to figure out what people's information needs are, on a personal level, and then say "Did you know you can do XYZ at the library?"
As for a retort on the Google comment, which we've all heard a hundred times, I say:
There're an enormous amount of resources on the Web, some of them relevant and valuable, and Google's very good at helping even the novice searcher get to them, but ... librarians are skilled & professional information organizers and retrievers; they go way beyond what Google can do. They help us better articulate what our questions or information needs are, help us understand what we're getting to on the Web when we get there (through Google or otherwise), how to use it, and what can be found beyond the Web, when necessary, to help us answer our information needs or inquiries more absolutely. (Not exactly short, is it?)
If you're just fact checking, gathering bits and pieces, Google is fine. But most of the time we want (and deserve) more than that.
Perhaps it sounds like I'm preaching to the choir...
