John Burnet's: Early Greek Philosophy (with notes)

It is probably the best work on Presocratic philosophers including their biographies, found fragments and commentary. Burnet, who is best known for his translation of Plato's works (the Platonis Opera Oxoniensis), was one of the greatest specialists in ancient philosophy and this can be seen by the accuracy of the information this book offers. However, it is not one of those professional studies that bore the reader and don't manage to transmit any information. Apart from some newly (XXth century) acquired information in the field (that may have occurred since Burnet wrote this book), "Early Greek Philosophers" offers to the amateur reader the best overview on Presocratic Philosophy.
