The project, founded in 1937 is now housed at the University of Sussex. It provides a valuable insight into the lives of regular people. The original work continued until the late 1950s.
The original archive which predominately covers 1937 - 1949, with some additions from the 1950s and 1960s is open to the public. Covering the period leading up to, during and for four years after the Second World War it does provide some really useful information of the social and domestic lives of individuals.
In 1981 the project was revived. In recent years a specific date has been selected - 12th May and anyone can email the project with what they did, ate, saw,read, wore etc.
You can read about the project via the website. You can read some of the entries from 12th May 2010 HERE. If you want to submit your entry for 12th May 2012 read the instructions HERE
I have just emailed my entry off to the email address provided on the instruction page. There appears not to be a closing date listed, so anyone reading this can probably send them in over the next few days.
