Several organisations and persons interested are working on the unique collection of Sailing Letters in the National Archives (Kew, UK) across the borders. They join forces in order to preserve the letters and make their contents available to the public.
The Royal Library started the Sailing Letters project in 2004. The project's goal is to increase the name of the Dutch documents in the archives of the High Court of Admiralty and to make them available to researchers. To this end the Royal Library collaberates with the National Archives (The Hague), Leiden University and the Cooperation of Maritime Funds (Samenwerkende Maritieme Fondsen).
The National Archives (TNA) are situated in Kew, London. Among the unnumerable historical documents that are being kept there are the boxes that contain the so called sailing letters. Without the benevolence of the TNA management and the help of the TNA members of staff it would be impossible to carry out extensive research into the sailing letters.
