New Harbinger Publications has acquired the publishing assets of Impact Publishers, publisher of popular and professional psychology books. The purchase involves about 125 titles, with 60 still in print.

Impact was founded 45 years ago by Robert Alberti, author of one of the company’s top sellers, Your Perfect Right. Other strong sellers include Anger Management for Everyone and Rebuilding. New Harbinger will continue to publish titles under the Impact imprint and expects to release additional new titles under the banner soon.

“We’ve watched with admiration over the years as New Harbinger has grown from similar roots—self-published book by a psychologist and colleague—to a very large and very successful publishing enterprise,” said Alberti, “Over the years we’ve often been approached by prospective buyers who found Impact an attractive investment prospect. New Harbinger is the first to offer such a natural blend of topics and markets.”
