When undertaking a research project, it may be a good idea to begin with some reference resources that provide background information on your topic. Subject-specific encyclopedias and handbooks provide useful and relevant overviews of a topic - they may also help you find a way to narrow your topic. Most encyclopedias and handbooks also include bibliographies at the end of each entry. These bibliographies will often list the "classic" or landmark articles on a topic.Citation searches can be done to find more recent articles that cite these landmark articles -- Ask a Librarian!
