IN 1987, THE Family History Department of the Church of the Latter Day Saints began a project with the British Genealogical Records Users Committee to transcribe and index the 1881 British census. Some community history societies were already creating indexes for the 1851 census, so they were well placed to take on another census project. Several tons of photocopies were distributed to almost 100 family history societies for double transcription and checking; later, a multi-million-dollar mainframe computer created indexes from the results (Young, 1996, 1998a; Tice, 1990). This ‘co-operative indexing’ took eight years – the process of assigning parts for transcription alone occupied 43 months – and while the project was very well received, in 1998 it was concluded that ‘a national project of this scope has proved too labour intensive, time consuming and expensive’ to be repeated (Young, 1998b). However, many years later, the US 1940 census was indexed in just four months by over 160,000 volunteers (1940 US Census Community Project, 2012), and co-operative historical projects flourish.

This example illustrates the long history of co-operative transcription and indexing projects, the significant contribution they made to the work of other historians and the vital role of community history organizations and volunteers in participatory heritage projects. The difference between the reach and efficiency of projects initiated in the 1980s and the 2010s also highlights the role of networked technologies in enabling wider participation in cooperative digitization projects. This chapter examines the important contributions of community historians to participatory heritage, discussing how family and local historians have voluntarily organized or contributed to projects to collect, digitize and publish historical sources about British history. This insight into grassroots projects may be useful for staff in cultural heritage institutions who encounter or seek to work with community historians.

The questions addressed in this chapter are drawn from research which sought to understand the impact of participatory digital history projects on users. This research involved reviewing a corpus of over 400 digital history projects, analysing those that aimed to collect, create or enhance records about historical materials. The corpus included both community- and institutionally led participatory history sites. Points of analysis included ‘microcopy’ (small pieces of text such as slogans, instructions and navigation) and the visible affordances, or website interface features, that encourage, allow or disable various participatory functions.
