In all of its many flavors, crowdsourcing works. It works for cultural heritage organizations too. During this presentation we look at various aspects of crowdsourced OCR text correction, commenting, and tagging for digitized historical newspapers at the National Library of Australia’s Trove, the California Digital Newspaper Collection (CDNC), and at the Cambridge Public Library in Cambridge Massachusetts as well as the astounding number of historical birth, death, marriage, census, and other records transcribed by “crowd” volunteers at Family Search. Some aspects include: demographics, experiences, motivation, quality, preferred data, economics and marketing. You will see that crowd sourcing is not only feasible but also practical and desirable. You will wonder why your own cultural heritage organization hasn't begun its own crowdsourcing project!
