Perhaps you should try some spelling variations:
bibliografie » bibliographie, bibliography, biografie
bibliografia » bibliographie, bibliography
bibliographic » bibliographie, bibliographical, bibliography
bibliographies » bibliographie, bibliographical, bibliography

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: (((bibliografie OR bibliografia) OR bibliographic) OR bibliographies).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((bibliografie OR bibliografia) or bibliographic) or bibliographies)".
• Adding a wildcard symbol may retrieve word variants: (((bibliografie OR bibliografia) or bibliographic) or bibliographies)*.
