The library recently added a subscription to Social Explorer, which provides easy online access to demographic information about the United States, from 1790 to present. It allows for the easy creation of thematic maps and downloading into other software products such as PowerPoint. It also provides convenient digital access to two censuses never before available online: 1970 and 1980.
You can find this on the databases A-Z list (go/databases); on some of the Research Guides; on the New & Trial Databases page go/trials or directly http://go/socialexplorer.
