Perhaps you should try some spelling variations:
"schriften des management" » "schriften des managements"
"schriften du management" » "schriften zu management", "schriften icu management", "schriften kmu management", "schriften d management", "schriften zur management"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("schriften du management") OR ("schriften des management"))*.
• Removing quotes may allow a broader search: (( schriften du management ) or ( schriften des management ))*.
