Office of Public Sector Information
N.B. On 29/7/10 the Legislation.gov.uk website was launched. It replaced the OPSI and Statute Law Database websites.
The Office of Public Sector Information has been part of the National Archives since October 2006, and Her Majesty’s Stationery Office (HMSO) is part of OPSI. The main content of the OPSI website is legislation as it was enacted, in its original wording. Although if the original wording of an old Act such as the Mental Health Act 1983 is required it must be purchased in paper format. Also, OPSI publish PDF files which make good printouts of new legislation. The OPSI website now contains some revised legislation.
