The coolest and most convenient app for any student, you scan the barcode of a book and select which citation you need (MLA, APA, Chicago, etc), and it automatically types it out for you! Unbelievably convenient. It saves so much time and stress! There are online sources like Citation Machine, but you have to manually enter everything. This app gives you everything you need in a quick shot of the barcode (similar to a QR-code reader). It also allows you to edit the fields to insert page numbers, etc. Go get it on the App Store! It’s free!
