Note: In addition to his books and magazine articles, Garrett P. Serviss wrote extensively for newspapers, having been a staff writer on the New York _Sun_ at the beginning of his career and having written later for a newspaper syndicate. This bibliography does not include any of Serviss' newspaper writings, with the exception of _Edison's Conquest of Mars_, since the effort involved in compiling a list of his writings from so ephemeral a medium would not be warranted by the questionable completeness of such a list, much of his writing for newspapers having been anonymous.
