The National Register of Archives for Scotland
(NRAS) was established by the National Records of Scotland (NRS), formerly the National Archives of Scotland (NAS), in 1946 to compile
a record of papers of historical significance in private hands in Scotland.
The principal aims of the NRAS are to locate such papers and to encourage
their care so that their loss and destruction may be avoided. The Register now
contains over 4,300 surveys of private papers including the records of landed
estates, private individuals, businesses, law firms and societies.
