The arrangement is as follows:
Volumes I-VII: Royal charters and others of the same period; these have been used by the editors of the ‘Regesta Regum Scottorum’, volumes 1-3.
Volumes VIII-XIII: Religious houses; there is no discernible order.
Volume XIV: Bishoprics; alphabetical.
Volume XV: Burghs and miscellanies.
Each volume has an identical printed title page, on whose verso is given biographical information on Lawrie.
The contents given for volumes XII-XIII are incomplete. A variety of papers has been used. Some leaves are numbered (often deleted). There appears to have been an older, radically different arrangement. Individual documents have not been indexed.
