Critically Analyzing Information Sources: Critical Appraisal and Analysis
Having made an initial appraisal, you should now examine the body of the source.
Read the preface to determine the author's intentions for the book.
Scan the table of contents and the index to get a broad overview of the material it covers.
Note whether bibliographies are included.
Read the chapters that specifically address your topic.
Reading the article abstract and scanning the table of contents of a journal or magazine issue is also useful.
What type of audience is the author addressing?
Is the publication aimed at a specialized or a general audience?
Is this source too elementary, too technical, too advanced, or just right for your needs?
Is the information covered fact, opinion, or propaganda?
It is not always easy to separate fact from opinion.
Facts can usually be verified.
Opinions, though they may be based on factual information, evolve from the interpretation of facts
Skilled writers can make you think their interpretations are facts.
Does the information appear to be valid and well-researched, or is it questionable and unsupported by evidence?
Assumptions should be reasonable.
Note errors or omissions.
Are the ideas and arguments in line with other works you have read on the same topic?
The more radically an author departs from the views of others in the same field, the more carefully and critically you should scrutinize their ideas.
Is the author's point of view objective and impartial?
Is the language free of emotion-arousing words and bias?
Does the work update other sources, substantiate other materials you have read, or add new information?
Does it extensively or marginally cover your topic?
You should explore enough sources to obtain a variety of viewpoints.
Is the material primary or secondary in nature?
Primary sources are the raw material of the research process.
Secondary sources are based on primary sources.
For example, if you were researching Konrad Adenauer's role in rebuilding West Germany after World War II, Adenauer's own writings would be one of many primary sources available on this topic. Others might include relevant government documents and contemporary German newspaper articles. Scholars use this primary material to help generate historical interpretations--a secondary source. Books, encyclopedia articles, and scholarly journal articles about Adenauer's role are considered secondary sources. In the sciences, journal articles and conference proceedings written by experimenters reporting the results of their research are primary documents. Choose both primary and secondary sources when you have the opportunity.
Is the publication organized logically?
Are the main points clearly presented?
Do you find the text easy to read, or is it stilted or choppy?
Is the author's argument repetitive?
Locate critical reviews of books in a reviewing source.
Is the review positive?
Is the book under review considered a valuable contribution to the field?
Does the reviewer mention other books that might be better? If so, locate these sources for more information on your topic.
Do the various reviewers agree on the value or attributes of the book or has it aroused controversy among the critics?
