'These notes have been prepared with meticulous care. Taken together these notes constitute a rich source book for the intellectual and cultural history of the first part of the nineteenth century. Each volume contains a detailed index, which makes it easy to use. No library specialising in the history of science and technology can disregard these volumes.'

'One of the most important publishing ventures in the history of science in recent years.'
