回复: 新手上路
I'd advise buying the CD version - that belongs to you permanently. The online account of annual subscription only allows you one year access if you pay 60 pounds.
BTW - you can register an trial account (the same service provided at the server at the British Library as if you paid) valid for 20 days free of charge! You will of course need to download a copy of SARA client programme (free again).
