Heron Books
Heron Books, Inc. is an assumed business name of Delphi Schools Inc., under which the company publishes many paperback books for teachers, students, and home schoolers, as well as single-subject dictionaries for all grade levels. It is a trademark owned by Northwest Research, Inc., which is another assumed business name of Delphi Schools Inc. Heron Books has its headquarters on the property of The Delphian School in unincorporated Yamhill County, Oregon, near Sheridan.
Several of Heron Books published works for students are based on the teachings of L. Ron Hubbard, the founder of Scientology. The Heron Basics Program is listed on the website of the Delphi Academy as their basis of instruction. Delphi Schools is a private school system licensed by Applied Scholastics, another Scientology-related entity.
Two other publishers have been called Heron Books, both based in London. One published faux-leather classics in the late 1960s and early 1970s while the other published new fiction and nonfiction as an imprint of Quercus from 2011 to 2016.
