Perhaps you should try some spelling variations:
"geschafte zu poetica" » "geschafte zur poetica", "geschafte fur poetica", "geschafte _ poetica", "geschafte la poetica", "geschafte de poetica", "geschafte a poetica"
"leithefte zu poetica" » "leithefte la poetica", "leithefte de poetica", "leithefte a poetica"
"leithefte e poetica" » "leithefte de poetica", "leithefte _ poetical", "leithefte a poetical"

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: (((("leithefte zu poetica") OR ("leithefte e poetica"))) OR ("geschafte zu poetica"))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"leithefte zu poetica\") OR (\"leithefte e poetica\"))) or (\"geschafte zu poetica\"))*".
• Removing quotes may allow a broader search: (((( leithefte zu poetica ) OR ( leithefte e poetica ))) or ( geschafte zu poetica ))*.
