Oxford University Press has a Dictionary of National Biographies which probably is also available in print, but can be accessed on-line at a premium. It contains biographies of some sixty thousand people in British history, from 400 BC to today. For promotion they have a podcast every fortnight Oxford Biographies that delivers spoken biographies in seven to fifteen minutes. (feed)
Each free issue is maintained for a limited amount of time in the feed. Names I have commented on in the past such as Roald Dahl and George Best, can no longer be had, but if you are quick PG Wodehouse can still be had, along with William Morris (of the Morris cars) and Hannah Snell an 18th century female soldier.
The latest issue, Agatha Christie, is also one not to miss out on. In nineteen minutes you will get every thing you need to know. How she was shy as a youngster, still loathed being a celebrity as an elderly woman, still such a prolific and successful writer and made a Dame by the end of her life. What I particularly liked was the attention given to her writing methods and the technique she applied to giving the clues, yet manipulating their ambiguity such that it would confuse the reader towards the wrong conclusion until the truth was revealed and the right solution to the whodunnit would be perfectly correct.
