I just wanted to let you know that to use EndNote Web off campus you will need to sign up to Web of Knowledge for a personal account (also known as web of science) you can then use the same username and password for EndNote Web becuase it recognises Web of Knowledge personal accounts.
EndNote is a database for storing and retrieving references. You can use EndNote to save references, insert citations into word processed documents and automatically compile reference lists in any chosen format.
I think EndNote web offers a perfectly acceptable version of Endnote to use, but without the fee – currently £83!
