BBC Radio 4 has a series of programs relating to history. Each program, compared by Melvyn Bragg, is just under 45 minutes in length. Recent programs can be listened to from the main page of the In Our Time web page, however the entire archive of previous programs is now available for downlaod from the In Our Time Archive - History. Downloaded programs are in MP3 format. The program on 1 November 2012 was on The Anarchy. Worth keeping an eye on.
