I learned about this site from a librarian on my PLN. We were doing #TLCHAT one evening and someone asked a question about citations. The librarian mentioned sending students to this site to record their information for their papers.
I actually sent a few kids there recently and they found it very simple to use and easily accessible. Users go there and create a citation for their topics. It generates a bibliography that is downloadable at the end. The student I sent there was very unaware of how to do a citation, but after I sat with him and walked him through it, he seemed pleased with how easy it was to use.
If you look at some of my screen shots, you will see how many different options there are for citation building. It covers all of the major book types.
The site itself is visually appealing and easy to use. There are several options available to use for your paper.
I encourage everyone to take a look at something such as CiteThisForMe as a way to organize and create an accurate works cited page.
