If you didn't find the help you needed on this guide, here are some additional options for help:

Ask A Librarian

  • The Ask a Librarian webpage offers an online chat service and a form to request a research appointment.  The online chat service is staffed by librarians and trained graduate students.  It's a great place to go if you need help right away.  Or, if you're on campus, just ask someone at the front desk of any library.
