What is in This Collection?

This collection contains records from BT (Board of Trade) record groups 348 - Registry of Shipping and Seamen: Register of Seamen, Central Index, Numerical Series; 349 - Registry of Shipping and Seamen: Register of Seamen, Central Index, Alphabetical Series; 350 - Registry of Shipping and Seamen: Register of Seamen, Special Index, Alphabetical Series; and 364 – Registry of Shipping and Seamen: Registers of Seamen, Combined Numerical Index.

This series is the combined numerical index of the Register of Seamen maintained by the Registrar General of Shipping and Seamen. The Central Register of Seamen originally consisted of three separate card indexes (CR1, central index, alphabetical registry; CR2, central index, numerical registry; and CR10, special index, alphabetical). The fourth index was compiled from its predecessors, for reasons unknown. According to the National Archives, cards in BT 364 dating from 1913 to 1921 were destroyed in 1969 for unknown reasons. Cards in BT 364 are arranged numerically by continuous discharge A number. The cards were filed by number, ignoring the letter prefix. At the end of the series is a small collection of un-numbered cards which have been sorted alphabetically by surname. Additional records and/or images may be added to this collection in the future.
