II. PRELIMINARY EVALUATION OF BOOKS AND PERIODICAL ARTICLES

By the time you reach Step 7 of the research process, you've used various access tools and come up with a list of citations for books, articles, and other traditionally published sources of information. At this point, it's important to do some preliminary evaluation of these sources even before you retrieve the book/article from the library shelves or database.

(NOTE: Websites are a relatively new way of presenting information that present a special set of challenges. Evaluating Websites will be discussed in the next section of this lesson.)

There are three ways to get a sense of the perspective, relevance, and quality of a book or article even before you have it in your hands:

  • Carefully examine the bibliographic citation.
  • Find information about the author.
  • Read a review of the work.

Let’s examine each separately.

1. Carefully examine the bibliographic citation.
(NOTE: This is the same as Step 6 of the research process.)

Bibliographic citations contain "clues" that will help you decide if an item is of sufficient quality and relevance and worth reading in its entirety. The clues are found in specific parts of the citation:

  • Title: Read the entire title of the book or article (especially the subtitle if there is one) and look for important words and phrases that indicate relevance to your topic. Also take note of the formality or informality of words used in the title. Formal language usually indicates a serious, scholarly work.

  • Author: Is this an author you've come across before in your reading? Is this author discussed or cited by other scholars or writers? If so, you can usually be certain that this person is important in the field. (The next section of this lesson will discuss how to find out more about an author's qualifications.)

  • Date of Publication: When was the item published? You usually want very current information if you're researching a topic in science, technology, or social science. By contrast, research on historical topics may benefit from primary or secondary sources written long ago.

  • Edition (for books): Publishers often revise books (especially textbooks) and issue them in later editions to reflect revised or expanded knowledge in the subject. A book that's continually republished in later editions is often an indication that it's become a standard, authoritative work in the field.

  • Publisher: Is the book or periodical published by a reputable publisher? University presses, (Harvard University Press, Stanford University Press, etc.) for example, are considered highly reputable and usually publish very scholarly material. Depending on your topic, you may also want to seek items published by what is known as the alternative press. The alternative press is comprised of small, lesser-known publishing houses that often make available unorthodox or controversial views from authors outside the academic mainstream. If you are uncertain about whether or not a publisher belongs to the alternative or mainstream press, ask the librarian or consult The International Directory of Little Magazines and Small Presses (REF Z6941.I32).

  • Abstract: Computerized periodical indexes often include a brief abstract (summary) that will help you decide if the article is relevant to your topic. Similarly, bibliographic records found on online catalogs sometimes have a field labeled "Contents" or "Summary" which will give you a better idea of what the book is about.

  • Subject headings: Books are given anywhere from 1 to 6 subject headings and should be read carefully because they describe the contents of the book. Similarly, computerized periodical indexes, such as the InfoTrac OneFile, assign subject headings to periodical articles.

  • Title of periodical (for magazine, journal and newspaper articles): Does your article appear in a popular magazine, scholarly journal, or professional publication? The distinction is important because each type of publication has a different audience in mind and will offer different levels of complexity and depth of analysis. The appropriateness of a popular, scholarly, or professional publication to your research depends on the type of information you need and your previous knowledge of the topic.

    It is also important to remember that periodicals often have an ideological perspective that may or may not be apparent from the title of the publication. In other words, magazines and journals often espouse a particular political stance or philosophical grounding, and the articles they publish usually express these perspectives and assumptions. For example, it's very helpful to know that Mother Jones is usually thought of as a magazine with politically leftist and socially liberal points of view and the articles they publish will reflect that ideology. On the other hand, National Review is thought of as a politically rightist and socially conservative magazine. To determine the ideological stance of a periodical, you can consult a publication called Magazines for Libraries, (READY REF Z6941.M23) or ask the librarian. Given below is a selective list of liberal, centrist, and conservative periodicals:
LIBERAL CENTRIST CONSERVATIVE
New Left Review Maclean's Policy Review
Mother Jones Economist Strategic Review
Monthly Review US News & Word Report Public Opinion
Progressive Time Cato Journal
Nation Newsweek Soldier of Fortune
New Statesman New Republic National Review

2. Find information about the author.

It is very important to know if the author(s) is qualified to write on your topic. The first step in assessing an author's qualifications is to ask yourself if you've seen this person's name before during your research. Respected authors are cited frequently by other scholars. If, however, it's a name you're seeing for the first time, you should try to identify the author's credentials. What is his/her educational background, past writings, occupation, experience, awards, and political perspective? Sometimes this information is provided on the first or last page of a journal article. In books, information on the author may be given at the beginning or end, or sometimes on the book jacket. Aside from the article or book itself, however, there are 4 ways to learn more about the background of an author:

  • Look for books about the author using the online catalog. If the author is an important literary figure or historically prominent, entire books may have been written about him or her. Conduct a subject search of the OPAC using the author's name as the subject.

  • Look for periodical articles about the author using periodical indexes. Magazines and newspapers frequently write articles profiling authors. These articles are included in general periodical indexes, such as the InfoTrac OneFile and in specialized indexes such as the Gale Biography Resource Center. A subject search (author's name entered last name first) will find entire articles about the author, while a keyword search (author's name entered first name first) will pull up any article in which your author's name is mentioned.

  • Search the Internet. Information about authors can be found in a variety of Internet articles and documents. When using a Web search engine to search for information about an author, enter the name in quotation marks, first name first. Also keep in mind that authors who are faculty members at colleges and universities often list their credentials at the school's Website.

  • Search specialized reference sources, such as:

    Contemporary Authors
    (REF Z1224.C6). One of the most comprehensive sources of biographical information on nontechnical writers of all genres -- fiction, nonfiction, poetry, drama, etc. - who have lived since 1900 and whose work has been published in the U.S. or translated into English. Covers over 90,000 modern writers. Contemporary Authors has reached over 100 volumes in print and Skyline Library owns a portion of the full set.

    Who's Who in America (REF E176.W642). Contains brief biographical information on individual Americans notable "by virtue of their positions and/or noteworthy achievements that have proven to be of significant value to society" (preface).

    American Men and Women of Science (REF Q141.A474). An 8-volume set providing biographical information about 119,618 scientists and engineers from North America who have made significant contributions in their field.

    Gale Biography Resource Center (online). A full-text database containing articles describing the life and work of thousands of noteworthy individuals, including authors, politicians, scientists, film makers, musicians, artists, and many others.

3. Read a review of the work.

Although not every book published is reviewed, it is often very helpful to find book reviews and learn what other people think about a book. Reviews summarize and critique the ideas presented in a book, thus giving you a deeper understanding of the work and helping you decide if it's relevant to your topic. (Journal articles are not reviewed in the same way that books are, but you can sometimes find a special type of article called a literature review that summarizes and discusses significant articles in a particular field or subject area.)

Book reviews are published in magazines, journals, newspapers, and on the Internet. They are indexed (listed) in most general and subject periodical indexes as well as newspaper indexes. When using the print versions of periodical indexes, books reviews are usually under a heading such as BOOKS; BOOKS AND LITERATURE, or in a separate section at the end of the volume labeled BOOK REVIEWS.

The best place to look for a book review, however, is an index that only lists book review articles. There are two such indexes:

Book Review Digest (BRD): Covering English-language fiction and non-fiction, the H.W. Wilson company began publishing this index in 1905. BRD is issued monthly with annual bound volumes and covers about 6,000 books per year. It offers a brief summary of each book listed along with citations for each magazine or newspaper review of that book. Short excerpts from the reviews are often included so you can immediately get a sense of the reviewer's opinion of the book. The reviews are drawn from 90 American, Canadian, and British magazines. Skyline Library has a complete set of the volumes in print, 1905 to the present, as well as an online version covering 1983 to the present.

Book Review Index: Published by Gale, Inc., this index covers many more books than Book Review Digest. Approximately 75,000 books reviewed in 500 periodicals are covered each year. Unlike Book Review Digest, however, no review excerpts or summaries are offered. Skyline Library has print volumes from 1969 to 1990. It is available online from 1969 to the present.

Finding book reviews can be a little complicated so feel free to ask the reference librarian for help.
