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": "(((( j currently nerve cyst dis ) OR ( i beta nerve case dti ))) OR ( j belval nerve cat did ))~".
• Se adicionar um carácter universal pode recuperar variações da palavra pesquisada: (((( j currently nerve cyst dis ) OR ( i beta nerve case dti ))) OR ( j belval nerve cat did ))*.
