Looking for a good book on linux & Libre

Hi Guys

Is there someone that can point me in the right direction?
At the moment I have got the kindle version of OpenSUSE 11.0 and SUSE Linux Enterprise Server Bible by Roger Whittaker and Justin Davies.
I see the book was published in 2008 & am a bit worried that it might be a bit out dated.
Can someone advise me on a good Linux book or manual?

Secondly I see the macro terminology on Libre is quite a bit different to windows.
Is there a good book or a forum where I can learn the correct terminology?

Try opening the following path in your web browser
That should open openSUSE manual for the version of openSUSE you have
same can be found here doc.opensuse.org - Documentation Guides & Manuals
For Libreoffice i found
LibreOffice API Documentation

Thanks vazhavandan
This is exactly what I am looking for.

you are welcome
