If you are looking for geology resources, the databases below are your best bets, though there are others.
GeoScienceWorld, which has GeoRef fully integrated into it, has a lot of content that you won't find in other databases (namely publications from geology societies) with very detailed search options/limiters. Searches can also be confined with a map feature. These search features aren't available in the GeoRef hosted in EBSCO.
ScienceDirect, covers an array of science, engineering and social science disciplines. It's easy to browse journals and it'll recommend articles to you. As this is an Elsevier product, some of their other products such as Mendeley and PlumX Metrics are integrated.
Web of Science has a broad focus. What's special about it is the citation tracking; it has a full list of the works cited by an article and a list of articles that cited it. This allows you to find useful resources via citations forward and backwards in time.
A small sampling of books in our collection. This will change periodically, so come back often!
