    3. 3. Why do we need to evaluate web sources? <ul><li>Virtually any person can publish almost anything on the Internet. </li></ul><ul><li>Unlike most print sources, web sources do not have to be professionally accepted and edited to be published. </li></ul>Purdue University Writing Lab

    13. 13. Identify the web site <ul><li>Whenever possible, try to locate the home page. </li></ul><ul><li>You can often do this by eliminating some information from the end of the URL. </li></ul><ul><ul><li>.org .gov </li></ul></ul><ul><ul><li>.com .net </li></ul></ul><ul><ul><li>.edu .us </li></ul></ul><ul><ul><li>.au .uk </li></ul></ul>Purdue University Writing Lab

How reliable is this material? </li></ul><ul><li>Are there links to other credible sites with additional information? </li></ul><ul><li>Does the site provide a link for emailing the author or webmaster? </li></ul>Purdue University Writing Lab

    19. 19. Determine depth and scope of information Purdue University Writing Lab <ul><ul><li>Are there a lot of flashy pictures, colors, animated images, and logos designed to attract attention? Do these eye-catching images distract you from noticing a lack of credible information? Do they disguise an attempt to get you to buy something? </li></ul></ul>
    20. 20. Determine depth and scope of information <ul><li>Different from print sources: </li></ul><ul><ul><li>Information covered on web pages is often presented for easy digestion and visual appeal. </li></ul></ul><ul><ul><li>Information may not provide sufficient depth or scope. </li></ul></ul><ul><ul><li>Material may be affected by marketing or political bias. </li></ul></ul><ul><li>Sometimes web sources may not be the right sources for the information you need. </li></ul>Purdue University Writing Lab

    22. 22. Assess date of information <ul><li>Does the site clearly state a date of creation or a date for the most recent update? </li></ul><ul><li>More importantly, does the information cover recent changes or advances in the field or topic you are researching? </li></ul>Purdue University Writing Lab
    23. 23.
