Perhaps you should try some spelling variations:
literatura del » literatura de, literatura el, letteratura del
literature del » literature model, literature does, literature dual
1 literatura » 1 literature, 1 literatur, y literatura
literatura a » literatura y, literatura e, literatura i
159 agenda » 1979 agenda, 1 agenda, 10 agenda
agenda ii » agenda iii, agenda i, agenda iv
6 agenda » 64 agenda, _ agenda, 7 agenda
ii a » ii _, i a
ii 1 » ii _, i 1

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: (( 159 agenda ii a ((literature del) OR (literatura del)) ) OR ( 6 agenda ii 1 literatura a )).
• Adding a wildcard symbol may retrieve word variants: (( 159 agenda ii a ((literature del) or (literatura del)) ) or ( 6 agenda ii 1 literatura a ))*.
