AnnoTate is a collaborative, online project that invites citizen and professional art historians alike to review and transcribe the sketchbooks, letters, diaries, and other personal papers that belonged to a number of famous British artists (including both British-born artists as well as those who immigrated to Britain). This project, a collaboration between the Tate Archives and Zooniverse, features over 52,000 items from the Tate Archives. These items include sketchbooks belonging to Eileen Agar, Francis Bacon, Joseph Herman, and Paul Nash, among others. Visitors can explore this collection by artist, and individual items belonging to each artist are accompanied by a short description and date. Those interested in helping with the transcription process may do so by selecting the transcribe button that accompanies items in need of transcription. New to transcribing text and images? No problem: once individuals select "transcribe," they can also view a short tutorial about the process. For all visitors (including those not interested in participating in the transcription project), AnnoTate offers a fascinating collection of primary documents that provide additional insight into a number of influential artists. Those who are interested in transcribing items will also want to check out the talk feature, which allows transcribers to problem-solve challenging transcription issues together.
