Google Scholar searches the full text of a wide variety of published and unpublished sources deemed "scholarly." These formats include traditional ones such as articles and book chapters, as well as theses/dissertations and "grey literature" from sources such as academic publishers, professional societies, and online repositories. With so many sources included, Google Scholar often retrieves a larger number of citations than other databases, so it can be a good place to get a broad overview of the existing research and identify core articles in a particular field.
