Working together with the British Library, the National Library of Medicine created this delightful digitized collection of "rare and beautiful" historical books in the biomedical sciences. The website is designed to complement their physical kiosks at the Library, and they have done a remarkable job with this project. The site contains six important texts, including Hieronymus Brunschwig's Liber de Arte Distillandi, a crucial work from 1521 on chemical, alchemical, and distillation devices. Actually, this volume is a good place to start one's explorations, and visitors will find that "turning" the digital pages is quite easy. After getting their feet wet, users can move on to look over Robert Hooke's Micrographia and Vesalius' seminal work, De Humani Corporis Fabrica.
