How I Use It
I use this site as a reference, both for myself and for my students. It's accurate and easy to navigate, provided you know what you're looking for. Students tend to get lost and frustrated because it is so specific.
There's a wealth of information here, but you have to know what you want. If you need to know how to cite a line from a song on a CD in MLA, it will tell you. You can't, however, just send students to the site without some guidance. As a reference for creating citations, it's great. As a teaching tool, it's too dry.
