Perhaps you should try some spelling variations:
nijhoff book » nijhoff boston, nijhoff op
ework title » work title, ebook title, work titles
title 2006 » title 20, title 2012
title 26 » title 21, title 25, title a
title 2 » title a, title 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: (( nijhoff ework title 2006 ) OR ((( nijhoff book ((title 26) OR (title 2)) ) OR ( nijhoff ework title _ )))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( nijhoff ework title 2006 ) or ((( nijhoff book ((title 26) OR (title 2)) ) or ( nijhoff ework title _ ))))".
• Adding a wildcard symbol may retrieve word variants: (( nijhoff ework title 2006 ) or ((( nijhoff book ((title 26) OR (title 2)) ) or ( nijhoff ework title _ ))))*.
