EasyBib is a great tool for creating bibliographies in MLA, APA or Chicago/Turabian style. What makes it even better than resources like Noodle Tools or Citation Machine is that, with Easy Bib, you can actually search the title of your source to see if a citation already exists. You can even search by ISBN number. Also, because this is a web application, your bibliography is saved online, so you can access it from work or home, and there is nothing to download. I'm currently using EasyBib for my Master's thesis, and I love how easy it is to use. There's even an option to add annotations to your entries for an annotated bibliography, and when all of the work is finished, EasyBib will turn your bibliography into a Word document.
