ABSTRACT
The author offers a philosophical, psychological and technical framework for approaching the components of crowdsourcing he see as compatible with the mission and values of cultural heritage organisations. In the process, he characterise a series of distinct components of crowdsourcing projects and suggest how, when thoughtfully deployed, these components offer some of the most meaningful ways that cultural heritage organisations can serve their missions on the web. Some of the projects that fit under the heading of crowdsourcing have chosen very different terms to describe themselves. The names of these projects highlight the extent to which they invite participation from members of the public who identify with particular professional occupations and their characteristic ways of thinking. Ben Brumfield runs a range of crowdsourcing transcription projects Human computation' is grounded in the fact that human beings are able to process particular kinds of information and make judgments in ways that computers cannot.
