Navigational publications provide extensive information relevant for the safety of navigation which cannot be represented on charts. They are published as occasional publications (Sailing Directions, Lists of Lights and Fog Signals, Nautical Tables, Radio Service) or periodicals (Nautical Almanac, Tide Tables). These publications are based on the data collected by the HHI, and other entities engaged in the safety of navigation, being produced according to the recommendations of the International Hydrographic Organisation.
Other publications include different scientific and technical editions covering maritime services, navigation, shipbuilding, maritime law, nautical tourism and economy, as well as Special editions series dealing with the history of navigation, hydrography and cartography in the Adriatic.
