The Stationery Office
TSO is a British publishing company that was created in 1996 when the publishing arm of Her Majesty's Stationery Office was privatised. TSO is the official publisher and the distributor for legislation, command and house papers, select committee reports, Hansard, and the London, Edinburgh and Belfast Gazettes. It publishes more than 9,000 titles in print and digital formats each year, making it one of the largest publishers in the UK by volume. TSO provides services, consultancy and infrastructure to deliver all aspects of the information lifecycle. TSO experts help to create, structure, capture, transform and deliver important information. TSO developed legislation.gov.uk with The National Archives, providing full access to the statute book as open data. The TSO OpenUp® platform is a collection of integrated services available as Software as a Service, with the aim of providing a highly scalable and resilient platform that allows organisations to store, query and enrich their data. In 2007, The Stationery Office was bought by Williams Lea. In 2006 Deutsche Post DHL, the leading logistics group, acquired a majority stake in Williams Lea.
