Google Scholar. Functions as both a key word database for articles and books. On campus it automatically connects to licensed content held by the UC libraries.
Google Books. Search the text of the books, view previews from books still in copyright, and read the full text of out-of-copyright books.
Citation or reference management tools help you manage your research, collect and cite sources, and create bibliographies in a variety of citation styles. Each one has its strengths and weaknesses.
