With Shelves, you can add items by scanning their barcodes, through Web searches, entering details manually, or by importing from or exporting to other sources (with full support for Delicious Library). Shelves organizes your collection with sorts, searches, and tags. You can loan items to friends in your contact list, or rate items for your personal use. Additionally, items can be in any language!
It's available for versions of Android 1.5 or higher. The website for the app is here: http://www.shelvesforandroid.com
