The ORR is a page that categorizes the electronic resources available to the UIUC community. It is best to choose the category at the top that most closely fits your need.
For example, it's best to search the Article Indexes category if you are looking for articles on a subject, rather than looking under Journals or All Resources (which only list titles).
Remember: if you need assistance contact a librarian: Ask A Librarian (http://www.library.uiuc.edu/askus/)
