Although the earliest surviving parliament roll dates from 1293, there are few original records earlier than 1466 and even thereafter there have been considerable losses. Most of the surviving records, apart from some records of the Committee of Estates for 1643-1650, some warrants and parliamentary papers, have been printed in the 'Acts of the Parliament of Scotland' (or APS), edited by T Thomson and C Innes (1814-1875). The series has a comprehensive index in volume 12.
Since the publication of this series, however, much new material has come to light. The Scottish Parliament Project, based at the University of St Andrews, has produced the Records of the Parliaments of Scotland to 1707 (RPS), a new digital edition of the proceedings published on the internet. The database supersedes APS and can be searched on the Records of the Scottish Parliament to 1707 website. For other information on the records of parliament, published sources and administrative history, consult 'The Guide to the National Archives of Scotland' (Stationery Office, 1996), pp 9-19.
