Talvez deva tentar algumas variações de ortografia:
reserve system » research system (Expandir a Pesquisa), research systems (Expandir a Pesquisa)
ventral nerve » femoral nerve (Expandir a Pesquisa)
cent reserve » debt reserve (Expandir a Pesquisa), men reserve (Expandir a Pesquisa), central reserve (Expandir a Pesquisa)
system due » system de (Expandir a Pesquisa), system der (Expandir a Pesquisa)
read nerve » treat nerve (Expandir a Pesquisa), end nerve (Expandir a Pesquisa), held nerve (Expandir a Pesquisa)
nerve cyst » nerve cat (Expandir a Pesquisa), nerve system (Expandir a Pesquisa)
i ventral » ii ventral (Expandir a Pesquisa), _ ventral (Expandir a Pesquisa), a ventral (Expandir a Pesquisa)
cyst dis » cyst due (Expandir a Pesquisa)
i cent » i cento (Expandir a Pesquisa), ai cent (Expandir a Pesquisa), ii cent (Expandir a Pesquisa)
j read » j reid (Expandir a Pesquisa), j reed (Expandir a Pesquisa)

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": "(((( i cent reserve system due ) OR ( i ventral nerve case due ))) OR ( j read nerve cyst dis ))~".
• Se adicionar um carácter universal pode recuperar variações da palavra pesquisada: (((( i cent reserve system due ) OR ( i ventral nerve case due ))) OR ( j read nerve cyst dis ))*.
