Look for the "Cited by" links in the Google Scholar search results in order to see a list of the articles and books the Google search engine has found that may have cited a particular resource. This can be very valuable for tracking down related articles and books.
Like the "Cited by" feature, the "Related articles" link leads to similar resources based on the Google algorithm.
You can use a variety of advanced search features by clicking the triangle icon in the search box for the "Advanced Scholar Search". You can search by title, author, or publication, as well as use Boolean operators. For complete information see Advanced Scholar Search Tips.
