Multiple computers /devices simultaneous log on details

A personal subscription allows just one user to gain online access at any one time. Therefore, it is important that you do not share your personal login details with third parties.

It also means that if you are logged in on one computer you will not be able to simultaneously log in on another computer. It is important, therefore, that when you finish a session you log out properly by selecting the 'Logout' button rather than just closing the browser using the 'X' button, otherwise may still recognise you as logged in for up to 30 minutes afterwards.

The 'Login/Logout' buttons are located in the top right corner of the page.

Academic institutions, research centers or companies should purchase a site licence which will enable multiple users to gain online access simultaneously. For further information you can submit a query to our Online Service team via our webform here. If you would rather email or phone them, their contact information is available here
