EasyBib is a bibliography and citation generator. Just type in your book title, newspaper, database, website, or journal and it will provide a WorksCited page in MLA, APA, or Chicago/Turabian style from their manuals. Each bibliography has a choice of being printed, saved, copied and pasted, or e-mailed to your paper or document.
The site also has an app for I-Phone and Android phones. This app allows you to scan the ISBN number of a book and it will automatically produce a citation for that book.
