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
