The Sacramento Bee’s Investigation Center
The Investigation Center includes both I-Tool Tips, a blog by the director of editorial research about interesting data sources on the Web, and a categorized database list that tells readers whether entry is one of the many databases produced by The Bee or a link to an outside source. There are also links to guides on the Freedom of Information Act and the California public records law, and a FOIA letter generator.
