This guide contains a brief list of resources that will be helpful as you begin your research: GeoRef, WorldCat, Web of Knowledge, and Marcive. You'll also find sample searches and tips tailored to each of your topics.
The contents of this guide are not exhaustive. For more databases and resources, visit the Geology research guide linked at the left. Don't forget to try different combinations of search terms. Also, be sure to consider synonyms for the search terms you decide to use.
If the library doesn't have an item you're looking for, don't forget to use interlibrary loan! Most items arrive in about two weeks, so plan accordingly.
