A poster advertising a 'Stop Trident' Easter demonstration in bold orange text, laid on top of a pink sheet of text titled 'The Mass Observation Project: Summer 2004 Directive'.

Welcome to Mass Observation Project. Launched in 1981 by the University of Sussex as a rebirth of the original 1937 Mass Observation, its founders' aim was to document the social history of Britain by recruiting volunteers to write about their lives and opinions. Still growing, it is one of the most important sources available for qualitative social data in the UK. 

This collection consists of the directives (questionnaires) sent out by Mass Observation between 1980 and 2010 and the thousands of responses to them from the hundreds of Mass Observers. 

Two leaflets and a typed directive. The first leaflet in yellow and says "AIDS: What you must know before you give blood". The second is red and advertises a 10% mortgage rate offer.

"If you're interested in the social, cultural and emotional pulse of Britain at the end of the twentieth century, Mass Observation Project is the obvious place to look. It is an extraordinary resource."
