Types of Periodicals

Periodicals have a variety of purposes and kinds of audiences. Magazines may be appropriate for some purposes, journals of opinion for others, but usually the most important sources for college level research are academic journals. The definitions below will help you understand these terms: Magazines are commercial publications intended for a general, popular audience for the purpose of informing and entertaining. Journals are specialized, scholarly publications written by authorities in the field. They usually include bibliographies. Subject or professional/practitioner magazines are between magazines and journals, with articles written by experts but intended less to advance the field than to report on developments of interest. Trade journals are also between magazines and journals, but their focus includes more product and business information.

Primary & Secondary Sources

Another distinction made about research materials is between primary and secondary sources: Primary sources–eyewitness accounts, laboratory data, interviews, original manuscripts, or original research, published in either paper or other formats that may include microform and electronic reproduction. Examples are diaries, letters, speeches, minutes of meetings, scientific research reports, and news footage. Secondary sources–works that interpret primary sources, and includes reviews, criticism, editorials, and analysis. Most journal articles are secondary sources that provide analysis, interpretation, or evaluation by the writer.
