Records of the Office of Public Works more than 30 years old have been transferred to the National Archives, Dublin. The types of public works records are described, then listed with call numbers.

“A compelling read” that reveals how maps became informational tools charting everything from epidemics to slavery (Journal of American History). In the nineteenth century, Americans began to use maps in radically new ways. For the first time, medical men mapped diseases to understand and prevent epidemics, natural scientists mapped climate and rainfall to uncover weather patterns, educators mapped the past to foster national loyalty among students, and Northerners mapped slavery to assess the power of the South. After the Civil War, federal agencies embraced statistical and thematic mapping in order to profile the ethnic, racial, economic, moral, and physical attributes of a reunified nation. By the end of the century, Congress had authorized a national archive of maps, an explicit recognition that old maps were not relics to be discarded but unique records of the nation’s past. All of these experiments involved the realization that maps were not just illustrations of data, but visual tools that were uniquely equipped to convey complex ideas and information. In Mapping the Nation, Susan Schulten charts how maps of epidemic disease, slavery, census statistics, the environment, and the past demonstrated the analytical potential of cartography, and in the process transformed the very meaning of a map. Today, statistical and thematic maps are so ubiquitous that we take for granted that data will be arranged cartographically. Whether for urban planning, public health, marketing, or political strategy, maps have become everyday tools of social organization, governance, and economics. The world we inhabit—saturated with maps and graphic information—grew out of this sea change in spatial thought and representation in the nineteenth century, when Americans learned to see themselves and their nation in new dimensions.

This guide is an updated version of Mandy Banton's indispensable introduction to the records of British government departments responsible for the administration of colonial affairs, and now held in The National Archives of the United Kingdom. It covers the period from about 1801 to 1966. It has been planned as a user-friendly guide concentrating on the organisation of the records, the information they are likely to provide and how to use the contemporary finding aids. It also provides an outline of the expansion of the British empire during the period and discusses the organisation of colonial governments.
