DeweyDigger gives TLs an interesting way to introduce the Dewey Decimal system. The opening page has a shifting slideshow for each of the 100s. Students can have fun guessing the category by looking at the images (although, there are some red herrings!) Across the top is a menu bar with each of the 100s listed. Selecting one of these tabs gives a very detailed breakdown of each topic. You can initiate a search by clicking on the sub categories, although the word cloud used for searching is not very sophisticated. The site is more of a novelty, but may be a different way to introduce, review or consolidate what your students know about the DD system.
