Ultimately, the Encyclopedia hopes to "serve as an online reference source and database for every one of the 1.8 million species that are named and known on this planet, as well as all those later discovered and described. Encyclopedia of Life will be used as both a teaching and a learning tool, helping scientists, educators, students, and the community at large gain a better understanding of this planet and all who inhabit it." Many resources are available already, however, this site always will be a work in progress.

According to the Touchspin (Design) Chemistry Web site, "Some other sites have more in depth information on chemistry, but I double-dog-dare-you to find anyplace with a better interactive periodic table.

When you're done, check out the site's new Biology area and find out what a horsefly's eye - or a pig's gall bladder -- look like under a microscope.
