I saw Google celebrating Dizzy Gillespie's Birthday a few weeks back. It was surprising I suppose, as he seems to have been largely forgotten. The popularisation of black american music and more importantly culture more or less starts with Dizzy Gillespie.
How many books does one person need - at any one time? I reckon probably less than 50. That includes cook books, design books, novels, travel books, language books etc. I mean if I'm stuck I can have any book on my desk within 48 hours.
