The Borthwick published the first complete guide to its holdings in 1973.
This was followed by two supplements, in 1980 and in 1997.
Although these are now out of date, and some of the arrangement of the archives has been, or will be, superseded, they are still useful as a historical record of how our holdings have developed since 1953.
Since 1995, information about new accessions to the archive has been submitted on a yearly basis to The National Archives.
To view our accessions by year and see how our holdings have grown visit the ARCHON directory.
