Give your employees a librarian.

Stephen Abram links to this article in a recent blog post. Amongst all the other wonderful office gift ideas to give is:

A librarian. Yes, I know, much of what you need is available online and your staff Googles with the best of them. Still, corporate librarians operate with a level of nuance and finesse that technology can't match. They can uncover sources so obscure as to be practically nonexistent. And they know what's what--they not only tell people what is known but also warn them what isn't.

Excellent.
