Perhaps you should try some spelling variations:
literature moral » literature more, literatura oral, literary moral
literatur ab » literatur a, literatur am, literatur a3
literatur a1 » literatur a, literatur am, literatur als
1979 agenda » 1979 wagenen
agenda ii » agenda iii, agenda iv, agenda _
agenda i » agenda _, agenda a, agenda 6
2 agenda » _ agenda, 7 agenda, 1 agenda
ii 1 » ii _, ii a, 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: (( 1979 agenda i a literature moral ) OR ( 2 agenda ii 1 ((literatur ab) OR (literatur a1)) ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( 1979 agenda i a literature moral ) or ( 2 agenda ii 1 ((literatur ab) OR (literatur a1)) ))*".
