The Encyclopedia of Life

Ultimately, the Encyclopedia will 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.
