The details of a day in the lives of hundreds of thousands of Britons will be recorded and compiled into a digital time capsule that will be stored permanently at the British Library, The Sunday Times reported.
The "One Day in History" project, described as a "blog for the national record", will feature British celebrities such as actors Stephen Fry and Derek Jacobi, and the writer Bill Bryson contributing to the compilation, along with any Briton with access to the Internet who wants to participate.
Students and teachers at 29,000 schools have also been invited to join in the project, along with pupils at the Dubai British School, who will blog about expatriate life in the Middle East. Any Briton who logs on to the website www.historymatters.co.uk can also submit their own contribution.
Anyone who participates is asked to submit between 100 and 1000 words about their day on Tuesday, in either English or Welsh the project was inspired by mass observation exercises conducted by sociologists through and since World War II to record the details of daily life.
"We want this day to have its own place in history and be a snapshot of everyday life at the beginning of the 21st century," said Fiona Reynolds, the director-general of the National Trust, which is organising the project.
