Aegean Park Press
Aegean Park Press is a publisher based in Walnut Creek, California, specializing in cryptology, military intelligence, contract bridge and Mayan languages. The company's books on cryptology are "mostly reprints of fairly advanced texts, "[i]ncluding at least 16 books by World War II cryptologists William F. Friedman, Lambros D. Callimahos, and Solomon Kullback. It has published more than 50 books related to cryptology and a smaller number of books on other areas such as military intelligence." It does most of its business by direct mail.
One of the company's ostensible customers has reported that it "ceased to exist either in lat[e] 2011 or early 2012"; the page at its URL was described in December 2012 as a "dead link" and carries, as of February 2014, the logotype and boilerplate of a domain registrar.
