Tertius Chandler's fringe-history books were issued by vanity/subsidy presses, placing them in a self-financed nonfiction register

The two books that carry Tertius Chandler's fringe historical claims were published by author-financed presses. Godly Kings and Early Ethics (1981) was issued by Exposition Press, and Moses and the Golden Age (1986) carries the 0-8059 ISBN prefix belonging to Dorrance Publishing Company. Both firms are documented, independently of Chandler, as subsidy/vanity presses: by 1956 Exposition Press was one of the three leading American vanity presses (with Vantage Press and Pageant Press, each issuing 100+ author-paid titles a year), and Dorrance describes itself as a "subsidy publisher of printed and ebooks," founded in 1920 after its founder's own manuscript was rejected by Scribners.

This answers part of the "in what register" branch of question-verify-chandler-pseudohistorian-attribution. These are not academic-press or peer-reviewed works; they are full-length, self-financed nonfiction books — a register distinct both from Chandler's urban-census scholarship, which mainstream demographers cite despite criticism of its sourcing, and from a passing aside. Full-length dedicated treatment argues that the theses were sincerely held rather than throwaway, though sincerity of tone within the text was not directly verified — no primary read was obtained (see claim-foldvary-remembrance-corroborates-chandler-fringe-claims). The publisher-type facts are definitional claims about the presses, the use a Tier-4 source is allowed to carry.
