In my field, many of the literatures are behind the paywall. Though my institute get subscription for most of them, I am sometimes not in the lab when I need to check something.
In such cases, usually VPN services could save my day, but I usually get impatient when VPN is connecting.
Luckily, my school also provide an alternative to use library proxy to
access those papers. It works by prepending the link of the paper with
http://proxy.library.some-university.edu/login?url=. This works quite
well for me except for the fact that I need to either type or copy-paste
this prefix every time.
