Orwell noted a few students have trouble with the Web site’s concept. “I’m sometimes asked ‘Are you a real person?’” he said. At other times, instead of reference-type questions, he’s greeted with more personal ones, from people looking to chat.

The librarians are trained to cut off communications at that point.

Orwell added that librarians aren’t allowed to give specific legal or medical advice. But they can direct people to other sources.

One of more interesting aspects of Ask Here PA is the ability of librarians to control what goes on to the computer screens of questioners. In a technique called “pushing the page,” Joseph said the librarian can cause Web sites with information to pop up on the screens of those seeking help.

That way, they need not go searching for it. Another miracle of modern technology — with a decidedly personal touch.
