What is the difference between a citation, abstract and full text?
"A citation identifies a book, periodical article, or other information resource. A citation will include the basic pieces of information necessary to allow you to find the article. That same information is used to create the list of references, or bibliography you will put in your research paper. Your instructor can then use the citations in the bibliography of your paper to identify and locate those same articles." http://libguides.uhv.edu/content.php?pid=334061&sid=2732422
