My colleague, Roberta Tipton, has created a Basic Guide for Undergraduates who are new to using the University Libraries resources. While it is focused toward students in English 102, there is still some important advice for you. The left column, in particular, has the essentials on "Access to Library Resources" under the Rutgers Libraries Catalog (IRIS) search box.
Are you feeling a bit concerned about searching journal indexes or any other aspects of library research? The University Libraries has a series of tutorials on the research guide, Research in the Disciplines, which includes sections on journal database searching and finding fulltext articles among other topics.
