Evaluation of Sources In Any Format: How to Evaluate

According to the Cornell University Library the primary objectives of students should searching for adequate research information should be The Author and what his/her credentials are, The Date of Publication, because in order to have adequate research the information you have obtained needs to be valid in this point in time and not outdated, The Publisher, the reason focusing on a publisher is important is because  a source published by a university or peer reviewed institution is more likely to be scholarly, and last but not least The Coverage of the Journal/Article because the student needs to know if the information they are obtaining from this source is primary, secondary, tertiary, or quaternary; the tertiary and quaternary sources can be discarded because they wont provide the student with as much appropriate levels of information for answer their research questions as will the primary and secondary sources.
