Ever since its first edition in 1898, Jane's Fighting Ships has been the go-to information source for navalists. As a result past issues of Jane's are an irreplaceable source of contemporaneous perspectives on the world's navies. Flipping through Jane's for 1898 or 1906 or 1939, you are seeing through the eyes of history. Unfortunately, most past editions are no longer in print and can only be obtained by purchasing used copies, which can be expensive and scarce, or via interlibrary loan, which can be slow and unreliable. The World's Warships were condensed wartime versions of the full editions of Jane's Fighting Ships that provided lists of ships by class and name, photographs, and basic particulars such as number of guns, while omitting the detailed technical information found in Fighting Ships. The 1915 edition was published in a 5.50 x 4.10" landscape format. Unfortunately, this likably compact format is not available from the large US print-on-demand vendors, so this reprint is published in 11" x 8.5" landscape with page images expanded to fit. This edition is annotated with a contemporary photograph of Fred T. Jane as a young man; a modern photograph of the "blue plaque" historical marker placed at the site of his residence in Southsea; and a second, modern preface written in 2022 from the point of view of the AI spirit of Fred T. Jane. 115 photographs and illustrations.
