One time a friend's daughter needed a an argricultural map of New Jersey. Hmm? That can't be too hard to find - right? WRONG! I refused to admit defeat. I called the Free Library of Philadelphia where I was connected to a delightful gentleman who couldn't have been more helpful. In about three minutes he not only found an argricultural map of New Jersey, he faxed it to me. Of course, this works for all kinds of information. Don't waste your time - call on a professional!
