Perhaps you should try some spelling variations:
visual literacy » digital literacy
vision library » design library, vision linear, asio library
visual library » virtual library, visual binary, visual lidar
gson library » open library, own library, town 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: %22theory AND ((((vision library) OR (((visual library) OR (visual literacy))))) OR (gson library))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22theory and ((((vision library) or (((visual library) OR (visual literacy))))) or (gson library))%22".
• Adding a wildcard symbol may retrieve word variants: %22theory and ((((vision library) or (((visual library) OR (visual literacy))))) or (gson library))%22*.
