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
file:///usr/share/doc/manual/opensuse-manuals_en/index.html
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
https://help.libreoffice.org/Common/Macro
LibreOffice API Documentation

Thanks vazhavandan
This is exactly what I am looking for.

you are welcome
