Perhaps you should try some spelling variations:
"nijhoff book titles" » "nijhoff boston titles", "nijhoff book intitled"
"nijhoff book entitled" » "nijhoff boston entitled"
"nijhoff op entitled" » "nijhoff one entitled", "nijhoff m.p entitled", "nijhoff now entitled", "nijhoff _ entitled", "nijhoff j entitled"

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 book titles") OR ((("nijhoff book entitled") OR ("nijhoff op entitled"))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"nijhoff book titles\") or (((\"nijhoff book entitled\") OR (\"nijhoff op entitled\"))))*".
• Removing quotes may allow a broader search: (( nijhoff book titles ) or ((( nijhoff book entitled ) OR ( nijhoff op entitled ))))*.
