They are possibly one of the best sources of naval study, images, and fellowship you can find.
The International Naval Research Organization is a non-profit corporation dedicated to the encouragement of the study of naval vessels and their histories, principally in the era of iron and steel warships (about 1860 to date). Its purpose is to provide information and a means of contact for those interested in warships.
With more than 50 years of scholarship, Warship International, the written tome of the INRO has published hundreds of articles, most of which are unique in their sweep and subject.
PRINT still has its place. If you LOVE warships you should belong.
