On this site you will find the manuscripts that record Charles Darwin's work as a practicing scientist. Whether you are a student or a researcher, our goal is to offer you digital access to the primary evidence for the birth and maturation of Darwin's attempts to explore and explain the natural world. In these documents, you can trace the development of Darwin as a thinker and you will meet Darwin as a keen-eyed collector, an inspired observer, and a determined experimenter. You will also find Darwin the shrewd reader, attuned to his cultural context, and the strategic writer, ever reconsidering and revising. The AMNH Darwin Manuscripts Project is a historical and textual edition of Charles Darwin's scientific manuscripts, designed from its inception as an online project. The database at its core—DARBASE—catalogues some 45,000 Darwin scientific manuscripts. These are currently represented by 15,125 high resolution digital images. Thus far 7,428 manuscript pages have been transcribed to exacting standards and all are presented in easy to read format. We will constantly be adding new material. So we would like you to think of us as an open workshop, where you'll be able to watch us at work. We are happy to train volunteers and interns at our office in the Research Library of the American Museum of Natural History.
