Google Scholar is a search engine created by Google in 2004 to allow students, researchers, and academics to easily search scholarly literature such as peer-reviewed papers, theses, books, and articles. It indexes millions of publications from university and private libraries that have partnered with Google Scholar. While it provides abstracts and citations for free, full texts often require a paid subscription. Advanced search features allow filtering results by date, author, publication, subject area, and more operators to refine searches. However, as a beta product, Google Scholar's database is still developing despite making academic research more convenient.
