Perhaps you should try some spelling variations:
specialist libraries » specialist librarians, spectral libraries
specific libraries » scientific libraries
special libraries » several libraries

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: academic & ((((specialist libraries) OR (((specific libraries) OR (specific injuries))))) OR (special libraries)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "academic & ((((specialist libraries) or (((specific libraries) OR (specific injuries))))) or (special libraries))".
• Adding a wildcard symbol may retrieve word variants: academic & ((((specialist libraries) or (((specific libraries) OR (specific injuries))))) or (special libraries))*.
