Finding Grey Literature

Finding Grey Literature

Official Publications

Libraries and Learning Resources hold large collections of UK official publications in printed form and online via FindIt@Bham. Some publications are freely available from government websites.  It is traditional to divide UK official publications into two main types: Parliamentary, which includes the devolved parliaments and assemblies, and Non-Parliamentary, e.g. the reports and other publications of individual government departments and agencies, such as the Department of Work and Pensions.

For more information on how to track down the different kinds of Official publications see the Official Publications guide.
