"The History Engine is an educational tool that gives students the opportunity to learn history by doing the work-researching, writing, and publishing-of a historian. The result is an ever-growing collection of historical articles or "episodes" that paints a wide-ranging portrait of life in the United States throughout its history and that is available to scholars, teachers, and the general public in our online database."
Turn a boring old spreadsheet into an interactive web-based map, timeline, or table with some simple HTML using the free, open source Exhibit project. Exhibit takes data sets up to about 500 rows, plots locations on a Google Map, dates on an interactive timeline, and displays images and links in a tabular or thumbnail view. The viewer can sort, search, and filter data in any Exhibit view without reloading the page. You can make Exhibit do all this with a single HTML file and a spreadsheet-no hardcore programming required.
