Oh wow, such great news!

Thank you!

Hi guys!

I am about self-publish a book and I have fallen in love with the font, Linux Libertine. The license stated on the page is Public Domain/GPL/OFL. I have tried researching what those three things mean but I still can't fully understand it. Can someone please help me? Am I allowed to use it in my publication? I tried looking for the contact person as well, but haven't found any clear information.

Any help/input will be greatly appreciated.

Thank you.
