  • Evaluating information sources for relevance – Article• Read the abstract.• Skim the introduction and conclusion, or if they are not marked by headings, skim the first six or seven paragraphs and the last four or five.• Skim for section headings, and read the first and last paragraphs of those sections.• Check the bibliography for titles relevant to your topic. 3
  • Evaluating information sources for relevance – Online• If it looks like a printed article, follow the steps for a journal article.• Skim sections labeled “introduction,” “overview,” “summary,” or the like. If there are none, look for a link labeled “About the Site” or something similar.• If the site has a link labeled “Site Map” or “Index,” check it for your key words and skim the referenced pages.• If the site has a “search” resource, type in your key words. 4
