52b. Selecting sources worth your time and attention

52bSelect sources worth your time and attention.

As you search for sources in databases, the library catalog, and search engines, you’re likely to get many more results than you can read or use. This section explains how to scan through the results for the most promising sources, and how to evaluate them as you preview them, to see whether they meet your needs.

Scanning search results

As you scan through a list of search results, watch for clues indicating whether a source might be useful for your purposes or not worth pursuing. You will need to use somewhat different strategies when scanning search results from a database, a library catalog, and a Web search engine.

Databases Most databases list at least the following information, which can help you decide if a source is relevant, current, and scholarly (see the chart at the bottom of this page).

Title and brief description (How relevant?)

Date (How current?)

Name of periodical or other publication (How scholarly?)

Length (How extensive in coverage?)

Many databases allow you to sort your list of results by relevance or date; sorting may help you scan the information more efficiently.

Library catalogs The library’s catalog usually lists basic information about books, periodicals, DVDs, and other material—enough to give you a first impression (see also 50d). As in database search results, the title and date of publication of books and other sources listed in the catalog will often be your first clues about whether the source is worth consulting. If a title looks interesting, you can click on it for information about the subject matter and length. For books or other long sources, such as reports, a table of contents may also be available.

Web search engines Reliable and unreliable sources live side-by-side online. As you scan through search results, look for the following clues about the probable relevance, currency, and reliability of a Web site.

The title, keywords, headings, and lead-in text (How relevant?)

A date (How current?)

An indication of the site’s sponsor or purpose (How reliable?)

The URL, especially the domain name extension: for example, .com, .edu, .gov, or .org (How relevant? How reliable?)

At the bottom of this page are a few of the results that student writer Luisa Mirano retrieved after typing the keywords childhood obesity into a search engine; she limited her search to works with those words in the title.

Mirano found the first site, sponsored by a research-based organization, promising enough to explore for her paper. The second and fourth sites held less promise because they seemed to offer popular rather than scholarly information. In addition, the second site was full of distracting advertisements. Mirano rejected the third source not because she doubted its reliability—in fact, research from the National Institutes of Health was what she hoped to find—but because a skim of its contents revealed that the information was too general for her purposes.

Previewing sources

Once you have decided that a source looks promising, preview it quickly to see whether it lives up to its promise. If you can evaluate as you search, rejecting irrelevant or unreliable sources before actually reading them, you will save yourself time.

Determining if a source is scholarly

For many college assignments, you will be asked to use scholarly sources. These are written by experts for a knowledgeable audience and usually go into more depth than books and articles written for a general audience. (Scholarly sources are sometimes called refereed or peer-reviewed because the work is evaluated by experts in the field before publication.) To determine if a source is scholarly, you should look for the following:

  • Formal language and presentation
  • Authors who are academics or scientists
  • Footnotes or a bibliography documenting the works cited by the author in the source
  • Original research and interpretation (rather than a summary of other people’s work)
  • Quotations from and analysis of primary sources (in humanities disciplines such as literature, history, and philosophy)
  • A description of research methods or a review of related research (in the sciences and social sciences)

note: In some databases, searches can be limited to refereed or peer-reviewed journals.
