Perhaps you should try some spelling variations:
nijhoff book » nijhoff boston, nijhoff op
ework title » ebook title, work titles, works title
book titles » book entitled, book intitled
work title » work time, work entitled, work intitled
titles 26 » titles 2.9, titles _, titles 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) OR (work title)) 2006 ) OR ((( nijhoff book titles 26 ) OR ( nijhoff ((ework title) OR (work title)) _ )))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( nijhoff ((ework title) OR (work title)) 2006 ) or ((( nijhoff book titles 26 ) or ( nijhoff ((ework title) OR (work title)) _ ))))".
• Adding a wildcard symbol may retrieve word variants: (( nijhoff ((ework title) OR (work title)) 2006 ) or ((( nijhoff book titles 26 ) or ( nijhoff ((ework title) OR (work title)) _ ))))*.
