Royal Society Publishing recently launched a new history of science platform. 

Science in the making that allows free access to digitised versions of over 30,000 archival items related to the publication of our journals from the past 400+ years.   

This is an extremely important and ambitious digitisation programme that presents the complex material that lies behind the published articles including reviews by Darwin, doodles by Newton, astronomical observations, electrical experiments, anatomical illustrations and more, drawing from every branch of science.
