Brief introduction / definition
Who hasn't used Google? The "Google" reflex when searching for information on the Internet is well established. Admittedly, this generalist search engine never disappoints in the first instance: thousands of responses are returned. But the relevance of these responses is a different matter.
To find only scientific and academic documents, there is a solution: Google Scholar! This tool allows you to limit your search to the scientific literature and to explore a part of the invisible web, which is inaccessible when using general search engines.
Google scholar: what is the content? What is the coverage?
History: Google Scholar was launched in 2004. It proposes peer-reviewed journal articles, pre-publication articles, books, theses, reports. It is a free service.
Sources: the indexed documents come from scientific publishers, learned societies, pre-print directories, university servers. However, Google Scholar does not give a list of its sources. Therefore, its limits remain quite vague.
Coverage: the database is multidisciplinary, but the natural and medical sciences resources are better covered than the humanities and social sciences.
Diverse document types: books, theses, scientific review articles, abstracts, proceedings, technical reports.
Languages: mostly English
