Zotero Mobile Apps Allow you Scan Books, Edit Library

I’ve mentioned several times how much I like and use Zotero, the “powerful, easy-to-use research tool that helps you gather, organize, and analyze sources and then share the results of your research.”
Capturing citation information from your computer has always been easy, but now there are some new mobile apps for Zotero that allow you capture content from the print world and work with your library on your mobile device.
Say that you’re in the library or bookstore and find a book that would be great for your research. With Scanner for Zotero (Android) or BibUp (iPhone) you can just scan the book’s barcode to add it to your Zotero library. I tried Scanner for Zotero and it worked great.
BibUp goes a step further by allowing you to scan (photograph) specific pages which it can convert to OCR.
Zandy (Android) allows you to edit and view your Zotero libraries, add new items, and work offline.

ZotFile Reader
(iPad, Android tablets etc) is a Firefox add-on that streamlines the process to work with Zotero and your pdf reader applications on tablet computers (iPad, Android tablet).
For more information on these apps, see the Zotero website.
Update 2/6/11: Thanks to Zandy developer Avram Lyon for letting me know that the link to Zandy was outdated. I’ve corrected it above. Avram also told me that the latest version of Zandy also supports reading attached PDFs and scanning barcodes.
