Nice collection, use this if you want to catalogue your collection... https://play.google.com/store/apps/details?id=com.dah.librarydvd it uses your camera to scan barcodes of your collection and then looks it up on the net (including covers). You can also custom edit everything there too and how you group them and then export them in a spreadsheet. Using it I found out that I now have 1298 DVD/Blu Ray's.
