The Weekly Reader Publishing Group, a division of Readers Digest since 2007, has sold the World Almanac imprint to Infobase Publishing, for undisclosed terms. Infobase president Mark McDonnell says in the announcement, “There are few names in reference publishing as well-known as the World Almanac, so when we had opportunity to add it to our existing family of imprints, we moved quickly. The World Almanac has been and will continue to be a powerful name in reference publishing, and we are excited about bringing it forward as an online resource as well.” Infobase’s imprints include Facts On File and Chelsea House.
