Perhaps you should try some spelling variations:
classical scores » classical sources, classical schemes, classical schools
classical bases » classical cases, classical case, classical phase
scores library » core library, codes library, forms library
closed library » chosen library, clone library, based library
cloud library » clock library, clone library, cloud libraries
bases library » based library, basis library, cases library

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: (( classical scores library ) OR ((( classical ((closed library) OR (cloud library)) ) OR ( classical bases library )))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( classical scores library ) or ((( classical ((closed library) OR (cloud library)) ) or ( classical bases library ))))".
• Adding a wildcard symbol may retrieve word variants: (( classical scores library ) or ((( classical ((closed library) OR (cloud library)) ) or ( classical bases library ))))*.
