The year of celebrations focussing on Charles Darwin concludes on 24 November with the 150th anniversary of the publication of On the Origin of Species by means of Natural Selection in 1859.

This is the moment to go back to Darwin's writing itself - to read exactly what he said, and to find out from contemporary sources just how big an impact it had. Gillian Beer's edition helps you do just that; James Secord's Evolutionary Writings gives you access to the whole range of Darwin's writings. And the selection of related books below brings you up to date on the science and thought that continues to flow from Darwin's insights, 150 years on.
