You have "fallen off" the proxy. The last page you requested is not in the list of resources that we provide access to. In order to use the proxy again, return to the proxy login page for the internal NRC-CISTI National Science Library website. Alternatively you can use the NRC proxy bookmarklet (a bookmarked application) which will also take you to the proxy login page.
To discontinue using the proxy during your web session, close and then reopen your browser window.
Possible Solutions:
When using a third party Internet Service Provider at home (e.g. AOL Canada, Rogers, etc.) via DSL, cable, ISDN, or regular modem, you will not be able to access NRC intranets or NRC-CISTI licensed resources, because you are not recognized as a NRC employee.
You will need to use the NRC Employees Proxy Server Login or, the NRC proxy server bookmarklet (bookmarked application) to access directly to your favourites from home.
Email alerts (e.g. journal Table of Contents email alerts) provided by some publishers and vendors contain web links to NRC-CISTI licensed full text content that are not properly suffixed for our proxy. For this reason, email alert services will no longer work remotely as clickable links, though they will continue to work properly if used from NRC networks with NRC IP addresses.
To access to these NRC-CISTI restricted licensed resources from outside of NRC, use the NRC proxy bookmarklet (bookmark application).
If you cannot access a licensed resource, NRC-CISTI may not have a license or there may be a problem with it. Ask NRC-CISTI for assistance on using the resource.
