scholarly & refereed
"Scholarly" and "refereed" are terms that describe the same thing -- research articles that are peer reviewed and published in scholarly journals. A research article reports a scholar's research practice and findings. It is written with an audience of researchers (and students, like you!) in mind and it must pass through the rigorous process of peer review.
popular & trade
Popular and trade magazines cover current events, general interests and industry specific topics. The audience for these periodicals are the general public or professionals in specific fields such as teachers, chefs, or healthcare workers. These resources tend to be larger in size and contain lots of glossy photos and advertisements.
Newspapers are written for the general public and typically articles are submitted by staff reporters or freelance journalists. Sources are sometimes cited, but not always. Newspapers are a good place to find current events and special features. They are usually published on a daily or weekly basis.
A reference work is a book or periodical (or its electronic equivalent) to refer to for quick, factual and background information. The writing style used is informative; the authors avoid use of the first person and facts are emphasized. Many reference works are compiled by a team of contributors whose work is coordinated by one or more editors. Reference works include dictionaries, thesauruses, encyclopedias, almanacs, bibliographies, and catalogs.
