Perhaps you should try some spelling variations:
reformation biography » information bibliography
bibliography sources » bibliography resources, biography sources, bibliographical sources
biography series » biography pericles, biography sources, biography sermons
early initiation » early integration, early instruction, early information
any reformation » many reformations, anti reformation, a reformation
early notation » early citation, early location, early innovation

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: (( any reformation biography series ) OR ( ((early notation) OR (early initiation)) bibliography sources )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( any reformation biography series ) or ( ((early notation) OR (early initiation)) bibliography sources ))".
• Adding a wildcard symbol may retrieve word variants: (( any reformation biography series ) or ( ((early notation) OR (early initiation)) bibliography sources ))*.
