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 et comme can netw ) OR ( j la computer case note ))) OR ( _ nad compr can netw ))~".
• Se adicionar um carácter universal pode recuperar variações da palavra pesquisada: (((( j et comme can netw ) OR ( j la computer case note ))) OR ( _ nad compr can netw ))*.
