I use the ngerman-package of babel in the main text part of my thesis and could manage to achieve a completely justified text by adding \usepackage{microtype}
In the bibliography the justification is violated. In order to justify items including URLs I managed to do so by setting a penalty: \setcounter{biburllcpenalty}{8000}
But in order to do so with item-titles too I only found \hyphenation{Lou-is-i-ana}
Is there already any more modern aproach and I just fail to find it?
