Perhaps you should try some spelling variations:
"monographie ion i" » "monographien band i" (Expand Search), "monographien der i" (Expand Search), "monographie ion g" (Expand Search)
"monographie von f" » "monographien band f" (Expand Search), "monographien der f" (Expand Search), "monographie von g" (Expand Search), "monographie von a" (Expand Search), "monographie von e" (Expand Search)
"geographie der i" » "monographien der i" (Expand Search), "geographie der _" (Expand Search), "geographie der 1" (Expand Search), "geographie der 2" (Expand Search)

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"monographie ion i\") OR (\"monographie von f\"))) OR (\"geographie der i\"))~".
• Removing quotes may allow a broader search: (((( monographie ion i ) OR ( monographie von f ))) OR ( geographie der i ))~.
• Adding a wildcard symbol may retrieve word variants: (((("monographie ion i") OR ("monographie von f"))) OR ("geographie der i"))*.
