GeoRef provides access to the geoscience literature of the world. Contains references to over 25,000 sources, including journal articles, books, maps, conference papers, reports, and theses. This database provides abstracts and then links out to the full text, so be sure to use the 'Exclude Abstracts Only' filter if you don't want to get results for conference proceedings where there is no article, since the abstract is all that exists!
An interdisciplinary journal archive. It includes archives of over one thousand leading academic journals across the humanities, social sciences, and sciences, as well as select monographs and other materials valuable for academic work. Includes the Artstor image collections.
Another useful feature of Google Scholar is its ability to allow for easily finding articles which have cited an article that you have found.
Step 1: When looking at search results, check for the 'Cited by X' link underneath each result. That will tell you how many subsequent articles (that Google Scholar is aware of...it's not 100% comprehensive! This is a ballpark figure) have cited this particular article.
