Reference sources are invaluable for defining key concepts, providing brief overviews of a subject, and identifying major theories and research developments. They can provide you with the background you need to select and develop a topic of research, or help you explore internship or career opportunities.
Reference sources are useful tools to obtain background information and to develop a vocabulary of possible search terms. The following items are available from the USM Libraries & other UMaine System Libraries. See the box at right for reference books available online.
