Electronic indexes often have more than one interface, which is the look and feel of the database, as well as several different vendors, which are the companies who package the information. Secondly, click on the yellow to the right of each listing to link to a comprehensive review of the specific features of each different search interface. While most indexes operate in the same fundamental way - you search for articles by looking up a particular subject, author, title, etc. There are guides available in both print and electronic formats which will help you navigate through many of the indexes available here at Cornell. Print guides are available in handout racks in all campus libraries.
Help is also always available within the electronic indexes.
Ask at a reference desk if you are having difficulty with a particular index.
