Infohawk+, the UI Libraries search interface, includes the books, movies and other material in the UI Libraries as well as journal articles from many of our databases. While that seems convenient, I think you are better off using Infohawk+ for books but bypassing it and going directly to research databases for journal articles. Use the tutorials in this tab to learn how to find and request books. Use the Finding Journal Articles tab for information on finding research articles.
