In 1902 the board of directors of F. M. Lupton Publishing Company changed its name to the Federal Book Company. This allowed F. M. Lupton, Publisher to continue printing periodicals and magazines, while Federal published books. Apparently this was to alleviate confusion between F. M. Lupton Publishing Company and F. M. Lupton, Publisher.

During this company's short lived existence Tom Brown books were only published in series form. Some of the series were continuations of the F. M. Lupton Publishing Company's series. http://henryaltemus.com/TomBrown/publishers/lupton.html
