At the Public Record Office, records are normally kept together according to
the department which created them.
The vast majority of records which relate
to the Navy are in the Admiralty or ADM lettercode. Within the lettercode each
collection, or class, of records is assigned a separate class number. Thus,
most navy widows' claims for back pay are to be found in class ADM 45. It is
these class numbers which are referred to throughout this guide.
The table below gives a summary of the major types of record available. For
a more comprehensive list see Roger, Naval Records for Genealogists.
