The Boston Public Library (BPL) is home to, "one of the largest and most important collections of abolitionist material in the United States," which includes thousands of letters, pamphlets, newspapers, and other materials from the early and mid-nineteenth century. BPL recently digitized this impressive collection on the platform Zooniverse and has enlisted citizen historians to transcribe these documents. In doing so, the BPL aims to create a collection that is freely available and machine-readable for those interested in pursuing digital research. Interested in helping out? Citizen historians will find a helpful tutorial in the transcribe section. In addition, this section of the website includes a helpful field guide to help participants with the task of interpreting nineteenth-century handwriting. The project also features a lively talk page where transcribers can crowdsource any questions that arise during the transcription process and share insights with fellow historians.
