Research can be a little stressful.
However, there are ways in which that stress can be lessened. Librarians will do their share to help cut down on the stress by providing access to quality library resources and by consulting with library users. Keep in mind that research is very time consuming. Plan on a minimum of four hours just for researching, printing and tracking down books and articles, and ordering others by interlibrary loan. If you give yourself more time to complete your research, unexpected delays won't cause as much of a problem.
