The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access.
An OpenURL link contains article metadata and directs it to the

search engine, export of references...). The OpenURL link can be
generated by different means.
If your librarian has set up your subscription with an

You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see
You should disable this module if you wish to use the OpenURL server that you or your library have defined.
