Critical Evaluation of ResourcesSuitability In the research process you will encounter many types of resources including books, articles and websites. But not everything you find on your topic will be suitable. How do you make sense of what is out there and evaluate its authority and appropriateness for your research? SuitabilityScope. What is the breadth of the article, book, website or other material? Is is a general work that provides an overview of the topic or is it specifically focused on only one aspect of your topic. Does the breadth of the work match your own expectations? Does the resource cover the right time period that you are interested in? Audience. Who is the intended audience for this source? Is the material too technical or too clinical? Is it too elementary or basic? You are more likely to retrieve articles written for the appropriate audience if you start off in the right index. For instance, to find resources listing the latest statistics on heart disease you may want to avoid the Medline database which will bring up articles designed for practicing clinicians rather than social science researchers. Timeliness. When was the source published? If it is a website, when was it last updated? Avoid using undated websites. Library catalogs and periodical indexes always indicate the publication date in the bibliograhic citation.
topAuthorityWho is the author? What are his or her academic credentials? What else has this author written? Sometimes information about the author is listed somewhere in the article. Other times, you may need to consult another resource to get background information on the author. Sometimes it helps to search the author's name in a general web search engine like Google. Among the reference sources available that list biographical information about authors and scholars are:
topOther IndicatorsDocumentation. A bibliography, along with footnotes, indicate that the author has consulted other sources and serves to authenticate the information that he or she is presenting. In websites, expect links or footnotes documenting sources, and referring to additional resources and other viewpoints. Objectivity. What point of view does the author represent? Is the article an editorial that is trying to argue a position? Is the website sponsored by a company or organization that advocates a certain philosophy? Is the article published in a magazine that has a particular editorial position? Consult these resources which indicate whether a publication is known to be conservative or progressive, or is affiliated with a particular advocacy group: Magazines for Libraries (Doe Reference AP1.21.K3 Directories) In the appendices to these volumes, consult the lists of Periodicals; then look up the names of sponsoring organization. Primary vs. secondary research. In determining the appropriateness of a resource, it may be helpful to determine whether it is primary research or secondary research.Primary research presents original research methods or findings for the first time. Examples include:
A secondary research does not present new research but rather provides a compilation or evaluation of previously presented material. Examples include:
Take an article in a popular magazine such as Mother Jones about the public health aspects of handgun control -- if it relies on interviews with experts and does not present any new research in the area, this article would be considered secondary research. If one of the experts interviewed in the Mother Jones article published a study in JAMA (The Journal of the American Medical Association) documenting for the first time the effect that handguns have on youth mortality rates, only the JAMA article would be considered primary research.
topReference SourcesBook reviews. A book review -- which can appear in a journal, magazine or newspaper -- provides a descriptive, evaluative discussion of a recently published book. Reading how others have evaluated a book may help you decide whether to use that book in your research. There are a number of indexes you can consult that provide references to book reviews: Book Review Digest (1905-current ) (Doe Reference Z1219.B8 Indexes). Online: 1905-1982 and 1983-current. UCB only Book Review Index (1965- ) (Doe Reference Z1035.A1.B6 Indexes) New York Review of Books (1963-current). Journal Indexes. You may also find reviews of books in many journal indexes by searching on the title and/or author of the book. Select a general journal index or an index for the subject area of the book. Citation indexes. To see the impact a particular source has had on scholarship, you may want to consult a citation index. A citation index lists when and where a work has been cited. In other words, you could consult a Citation Index to see all the articles that have cited David Ho's research on HIV. The citation indexes are all available in the following database: Web of Science: http://isiknowledge.com/wos Science Citation Index (1945-present) Social Sciences Citation Index (1970-present) Arts & Humanities Citation Index (1975-present) topLinksThe Good, The Bad & The Ugly: Or, Why It's a Good Idea to Evaluate Web Sources. From New Mexico State University, this guide includes links to examples of both "good" and "bad" websites. How to Critically Analyze Information Sources. A quick guide to help you determine the relevance and authority of a resource. A useful companion guide is one titled Distinguishing Scholarly Journals from Other Periodicals. Both from Cornell University. Evaluating Information Found on the Internet. A thoughtful guide to evaluating web and other Internet resources for scholarly purposes, from John Hopkins University Library. Evaluation of Information Sources is an extensive list of links to the many other sites available on evaluating information. top
