- to credit an author's original idea or information - to avoid plagiarism - to organize source material - to direct reader to sources to learn more
I think all of these points are true and indeed helpful in any paper or essay. They should be considered, and added. Those are all the purposes of a work- cited page.
A page in an assignment or paper that cites all the websites and sources ou used is very important, and often is underestimated. First, and most importantly, you do it to credit the author's original idea. It was their work, and they deserve to be credited for it. Next, you do it to avoid plagiarism. Most schools give out 0's for plagiarism, and if you're publishing it, you can get sued. It can also be used to organize source material, and that leads me into my next point, how it directs readers to sources to learn more. If all the sources are organized, it's better for the keen reader who wants more info. Hope this helped!
