Perhaps you should try some spelling variations:
"johann gottfried fichte" » "johann gottfried michael", "johann gottlieb fichte", "johann gottfried biewe"
"johann gottfried biewer" » "johann gottfried biewe", "johann gottfried peter", "johann gottfried herder"

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: (("johann gottfried fichte") OR ("johann gottfried biewer"))*.
• Removing quotes may allow a broader search: (( johann gottfried fichte ) or ( johann gottfried biewer ))*.
