I published Legal Foundations of a Free Society (Houston, Texas: Papinian Press, 2023) last September, in hardcover, soft cover, and Kindle formats. A free pdf was released at the time of publication as well and the book was published under at CC0 (no rights reserved) license.
A second printing, with corrections of accumulated errata, has just been released (August 2024; no change to pagination). A free epub file, including all errata corrected to date, is now available for download as well.
