The creators of the Information, Please! radio show saw a need for a reference book with answers to the type of questions they received on the show, and they began publishing the Information Please Almanac in 1947. The almanac has been published annually from 1947 to the present with a variety of publishers, including Viking, Simon and Shuster, Houghton Mifflin, and McGraw-Hill. Since 1997, Information Please has partnered with TIME in publishing the almanac as The TIME Almanac with Information Please.

Over the years, a variety of other Information Please almanacs have been published, including:
