An outstanding fact of modern life is the increasing need of specific knowledge of all kinds. In nearly every home there is a frequent quest for authoritative information that will dispose of a moot point seen in the press, heard on the radio, or discussed among the members of the family. Even more constant is the need for practical information essential in the running of the home and in the understanding of the business world. For these purposes many reference works are available. But they are voluminous and costly, or they are too highly specialized. It is to meet this need for a compact and inexpensive volume that 'The Handy Encyclopedia Of Useful Information' has been prepared.
