Mendeley released a nice feature a while back that allows you to find the article you are currently browsing in full text via your library. Autodetection doesn't work but by adding the proxy version of our openurl directory, you can access this feature from anywhere. Just manually add a new external library in Mendeley options using the URL below.

Note that you need to log in with your LNU username and password.
Credits to Simon at infontology for bringing this feature to my attention
