Here is a continuously growing list of earth science links I have found by net surfing. I don't know how often I will attempt to update them. If you have a link you want me to include or have some information about updating a link then send me mail and let me know. The best all around list for earth science resources I have seen so far is the Earth/Geoscience Information Sever by Russ Jacobson.
