It is harder to find online versions of documents produced by or for government departments but which are not presented to Parliament. Current documents will usually appear on the website of the government department concerned, but sometimes documents have moved or departments have changed names and/or web addresses.
The UK Government Web Archive http://www.nationalarchives.gov.uk/webarchive/ part of the National Archives is working to mitigate the effects of such changes.
Not all House of Lords papers and bills may be online.
Official publications are documents published by national governments or by inter-governmental organisations, such as the United Nations and the European Union.
It is traditional to divide UK official publications into two main types: Parliamentary and Non-Parliamentary. Parliamentary papers are a product of the work of the UK Parliament and also of the devolved parliaments and assemblies. Non parliamentary papers are the reports and other publications of individual government departments and agencies, such as the Department of Work and Pensions and the Highways Agency.
Please note that many of the major online resources eg UK Parliamentary Papers are only available to you if you logon to FindIt@Bham with your University username and password using the Sign in link at the top right of the screen.
