               BibMe: Fast and Easy Bibliography Maker

    Here's how it works:  You just scan the book's barcode with your phone and, through the magic of technology, your correctly formatted citation appears!  Then, just proceed to the next book.  You also have your choice of formatting in MLA, APA, or Chicago styles!  After you've completed your citations, just select all, and then you can email to yourself (or to anyone else if you so desire).  Just copy and paste into a Word document, etc., or you have the option to save each citation to EasyBib's on-line citation maker!  How simple is that!  And by the way, even without the app, the EasyBib on-line citation maker is also so simple that all you have to do is enter a book's International Standard Book Number (ISBN) or a web address to format for free in MLA style!
