The Green Oak Press Difference We’re authors. We recognize the emotional journey each author travels whilst completing their work. It is our goal to work in concert with our authors, providing them an integrated role in the publishing process. Unlike other publishing firms, Green Oak Press has a publisher, John Errigo has published six books of his own, and produced and published four famous public domain books, through his own self-publishing platform, Quicentennial Publishing Co. Our Leadership Team is committed to seeing our authors succeed and ensuring they receive the royalties they deserve. All Green Oak Press authors earn a hefty percent of the royalties their publication earns. While Green Oak Press is headquartered in the United States, we consider ourselves a global firm and seek out authors from all over the world. We are able to publish your book in your native tongue, but it is company policy to publish manuscripts in English or Spanish first.
