Perhaps you should try some spelling variations:
information bibliography » notation bibliography, introduction bibliography, approximation bibliography
bibliography resources » bibliography references
bibliography sources » bibliographical sources, bibliography journals, bibliography indices
many reformations » _ reformations, many generations, many revolutions
early information » early formation, early integration, early instruction

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: (( many reformations ((biography sources) OR (bibliography resources)) ) OR ( early information bibliography sources )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( many reformations ((biography sources) OR (bibliography resources)) ) or ( early information bibliography sources ))".
• Adding a wildcard symbol may retrieve word variants: (( many reformations ((biography sources) OR (bibliography resources)) ) or ( early information bibliography sources ))*.
