looking for best barcode scanner library, besides zxing [closed]

I am looking for some best barcode libraries on all platforms. I know zxing but wondering more libraries besides it. Any help is appreciated~

In which library services barcode technology is generally used?

Barcode technology is mostly used in the circulation system of a library and most successful due to its speed, accuracy and reliability.

Jeff Lamarche's Cocoa Barcodes project for iPhone and iPad

Zxing's barcode image process library

Android barcode library

ISBN & QR Barcode Scanning Mobile App for Libraries

As nithin mention Barcode scanner libraries, one more I would like to add ZBar Barcode Library.

http://zbar.sourceforge.net/

This also contains support for various platform. And it is Open Source.
