Perhaps you should try some spelling variations:
visual literacy » digital literacy
virtual library » virtual laboratory
visual library » visual binary, israel library, visual diary
visual lidar » visual aids, visual aid, visual light
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 ((((((((visual library) OR (visual literacy))) OR (visual lidar))) OR (virtual library))) OR (gson library))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22theory and ((((((((visual library) OR (visual literacy))) or (visual lidar))) or (virtual library))) or (gson library))%22".
• Adding a wildcard symbol may retrieve word variants: %22theory and ((((((((visual library) OR (visual literacy))) or (visual lidar))) or (virtual library))) or (gson library))%22*.
