1) Accuracy. Verify the information you already know against the information found in the source. Look also for disclaimers as to the accuracy of the content. You may also want to double-check the information against a source that you already know is trustworthy. Even though a source may use technical language, the content may be misleading.
2) Authority. Make sure the source is written by a trustworthy author and/or institution. If you are using a webpage, you can usually identify the owner/publisher by the URL, or check for a copyright statement near the bottom of the page. Make sure the author has the proper credentials on the subject matter. Also, determine if the source is biased. For example, if it is medical information from a drug company, that company will provide information in support of its product. Be aware of the objectivity of the author and his/her viewpoints.
3) Currency. Depending on your subject, your currency needs will vary. For topics related to recent breakthroughs in medicine and technology, you will need to find up-to-date sources. If, however, you are researching a historical topic, older resources may still be useful. For webpages, you can often find a copyright date near the bottom. Also, look for the words "revised" or "updated" to find the date of the website.
