History
Janes was founded in 1898 by Fred T. Jane, who had begun sketching ships as an enthusiast naval artist while living in Portsmouth. This gradually developed into an encyclopedic knowledge, culminating in the publishing of Janes Fighting Ships (1898).<ref>Template:Cite book</ref> The company then gradually branched out into other areas of military expertise. The books and trade magazines published by the company are often considered the de facto public source of information on warfare and transportation systems.
