Google Scholar is a freely-accessible Web search engine that indexes the full text of scholarly literature across an array of publishing formats and disciplines. The index includes most peer-reviewed online journals of the world's largest scientific publishers. Its advertising slogan — "Stand on the shoulders of giants" (paraphrasing a quotation from Isaac Newton) — is a nod to the scholars who have contributed to their fields over the centuries, providing the foundation for new intellectual achievements.

Cool
Google Scholar has been indispensable for my research this semester and so many semesters before. The breadth of features is not immediately obvious, but they are quite useful: finding related articles, restricting the time period, seeing all texts that cite a given article and so on. I find I prefer the relative simplicity of the interface to the common alternatives (such as Academic Search Premier and Web of Science,) but wish there was a built-in way to manage my sources. Finally, the ability to associate with a university (and, thus, its subscriptions to academic databases) means I don't have to waste as much time tracking down electronic or hard copies elsewhere.
I like this! I appeared out of some link I clicked... just like Google Blog Search.
Great site for finding articles on really specific topics, also 'related to' function is great, sometimes also helps to find a free copy of an other wise expensive pdf document; every student and scholar should (at least) know about it!
Average site.
Very useful for research.
