Git book questions

Hello,

I'm searching for books about Git and found the following ones:

1. "Pragmatic Version Control Using Git"
<http://www.pragprog.com/titles/tsgit/pragmatic-version-control-using-git>

2. "Git Internals"
<http://peepcode.com/products/git-internals-pdf>


Unfortunately I could not find out, whether the "undoing" of Git Actions 
is fully covered in those (in my mind this belongs to everyday actions).

I'm thinking of

* undoing git add / rm / mv
* undoing local changes
* undoing committed changes

which I found less intuitive looking at the Git commands ('git reset', 
'git revert' might not do what a beginner expects or multiple actions 
might be necessary).

If somebody of you owns a copy of the above mentioned books could you 
please kindly let me know whether the topics are covered in detail?

I would also appreciate review comments or hints to other books, if you 
have any.

Thanks in advance for your help.

Regards

Guido
