A complete listing of charts issued by the Oceanographic Office as of February 1972, including most importantly the cross-referencing of old H.O. and National Ocean Survey C.S. numbers with the later N.O. number scheme. This N.O. chart number scheme is the foundation for DMA/NIMA/NGA chart numbering.
