Just checking out some of the awesomme IMS sites developed and maintained by Latitude Geographics. For a great example check out this Public Library Geographic Database (PLGDB) Mapping website at Florida State University - http://plgdb.freac.fsu.edu/. The interface is slick and simple. Nice, friendly features like adding bookmarks, print to PDF and grab data make the site quite useful. Check out an area of interest for numerous data themes and variables.
