DeweyBrowser

No, it's not the next rival to IE (thought it is way cooler, imho).  Check out the DeweyBrowser, a visual interface that lets you browse for resources based on subject headings and DDC numbers.

You can start with a search and then get a color-coded display of which of the ten main DDC classes have results for your search (and how many in each).  You can also start with a straight browse, choosing one of the ten main classes.  You then get to drill down two more levels, everything color-coded for relevance, and quickly see where the relevant records will be.

Too much fun for a librarian.
