Reference Books

Includes:

  • Dictionaries
  • Encyclopedias
  • Handbooks
  • Yearbooks

General and subject-specific reference books provide brief overviews or summaries on any given topic. They can include background information, factual data, key ideas, important dates, and concepts.

  • If you know very little about your topic, reference sources are an excellent place to start research.

Circulating Books

Includes:

  • Fiction
  • Nonfiction

Books typically provide an in-depth examination of any given topic, usually from a retrospective point of view. Research-oriented books are works of non-fiction.  Fiction works include novels, short stories, and poetry.

If you need:

  • Historical and detailed information on a subject, such as the United States Civil War.
  • To put your topic in context with other important issues.
  • Several points of view in one book such as collected critical essays on Shakespeare’s works.

Journal Articles

Also known as:

  • Peer-reviewed articles
  • Refereed articles
  • Scholarly articles

Journal articles provide in-depth research on very specific topics. Journals cover a wide variety of disciplines. Articles are written by experts in the field and use vocabulary or jargon from a particular field of study. In addition, articles usually have cited references that will point you to other relevant research. Journal articles tend to be lengthy and are typically published on a monthly or quarterly basis.

If you need:

  • Scholarly articles or original research
  • To find out what has been studied on your topic
  • References that point to other relevant research.

Magazine & Newspaper Articles

Also known as:

  • Popular articles

Magazine and newspaper articles provide up-to-date information on the latest developments on various issues or current events. Issues and events covered can be local, regional, national, and worldwide. Articles are usually written by freelance writers and many times articles can be unsigned. Articles are written for a general audience and contain simpler vocabulary. Articles tend to be short in length and are typically published on a daily (newspapers), weekly or monthly basis (magazines).
