Logging in ext3 - Documentation

I was looking for documentation on how journaling is implemented in ext3 and cannot find any good resources. I am familiar with ext2 internal components and implemented them on Linux and Minix.

Could you point me to resources / code snippets that could help me understand the implementation of logging in ext3?

This is not exactly how Ext3 logging works, but the preliminary work I find interesting is: http://original.jamesthornton.com/hotlist/linux-filesystems/ext3-journal-design.pdf

Ext3, : http://olstrans.sourceforge.net/release/OLS2000-ext3/OLS2000-ext3.html
