Popular Magazines

• Are written for a general broad audience.

• The information may or may not be written by an expert in the field.

• Articles are often by a staff writer and contain quotes & opinions of experts.

• Often contain well-considered writing.

Is this a good source for a research paper?

• When evaluating a source to use in a research paper, the degree of authority and the depth of research on a given topic determine if the source has academic value

Academic Journals… A better Choice?

• Scholarly sources contain articles written by experts in particular fields.

• Experts are recognized by their degrees, work affiliation, and research publications.

• Subject-specific.

• Critically evaluated by peers (fellow scholars) for content, scholarly soundness & academic value.

Examples

• JAMA: The Journal of the American Medical Association

• School Library Journal

• Modern Fiction Studies

• American Anthropologist

How do historians research?

• They tend to do more solitary research.

• They read books.• They get direction

from citations in their reading.

• They use primary sources and back them up with secondary sources.

Consider as you do history research

• Use both primary and secondary sources

How do Scientists Research?

• Go to seminars & professional meetings and talk with other scientists.

• Do their own experiments.

• They subscribe to journals in their field of study.

How do Scientists Research?

• Scientists are concerned with the results of other’s research.

• They go to peer-reviewed journals like Nature to read original research results.

“But not every article in Nature or Science Journal will be original research!

A Word of Caution:

• Not every article in the journals will be research articles. Some will include book reviews and other materials that are more obviously secondary sources.

• (Remember: a secondary source is something written about a primary source. Secondary sources include comments on, interpretations of, or discussions about the original material).

• Review articles are more difficult to differentiate from original articles. They are not primary sources because they “review” previously published materials.

In the Sciences,

• Primary literature refers to the first place a scientist publishes the results of scientific investigations.

How can you tell if it’s original research (or a primary source?)

Primary research articles use a common format:

• Look for a methods section (sometimes called materials & methods).

• Look for results (usually followed with charts & statistical tables).

• Look for a discussion section.• Look for language like “we tested”, “in our

study” or “we measured.” This tells you the article is reporting original research.

Where the Confusion Begins…

• The distinction between types of sources can get tricky because a secondary source may also be a primary source.

• Gary Wills’ book about Lincoln’s Gettysburg Address can be looked at as both a secondary and a primary source. The distinction may depend upon how you are using the source and the nature of your research.

Primary or Secondary?

• If you are researching about Abraham Lincoln, the book would be a secondary source because Wills’ is offering his opinions about Lincoln and the Gettysburg Address.

• If you are researching the Gettysburg Address, this original primary source document is contained in Wills’ book.

Primary or Secondary?

• Primary literature refers to the first place a scientist publishes the results of scientific investigations.

In the case of a

scientific journal,

the author may

have first published

their original researchIn the Journal of Zoology

If the article isrepublished in Nature, it is no longer a primary source.
