You can also try:

• Europeana
• Digital Public Library of America
• CORE

Pode obter mais resultados ajustando a pesquisa.

• "As palabras AND, OR e NOT podem gerar pesquisas incorrectas; tente utilizar aspas": "(((( a cent nerve based diets ) OR ( i ventral eye can tdcs ))) OR ( j benito narvaez fat diets ))~".
• Se adicionar um carácter universal pode recuperar variações da palavra pesquisada: (((( a cent nerve based diets ) OR ( i ventral eye can tdcs ))) OR ( j benito narvaez fat diets ))*.
