Perhaps you should try some spelling variations:
litterature sarda » letteratura sarda, litterature par, litterature serbe
land litterature » la litterature, land literatur, und litteratur
di letteratura » e letteratura, della letteratura
de literatura » de litterature, la literatura, y literatura
grund libro » gran libro, und libro
grunde die » grunde der, grunde des, grundlage die
die land » die lander, die lange
i grund » i ground, i grand

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: (( i grund libro ((di letteratura) OR (de literatura)) fra ) OR ( i grunde die land litterature sarda ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( i grund libro ((di letteratura) OR (de literatura)) fra ) or ( i grunde die land litterature sarda ))*".
