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!
