Using the KTHB proxyAccessing journals from outside KTH can be difficult, but thankfully, KTHB has a proxy that you can go through from wherever you are. You simply login to the KTH web and access journals (and other resources) through the KTHB website.
Trick historyAymeric Fouquier d'Herouel taught me a URL-based trick which I turned into a conventient bookmarklet. This served me and colleagues for several years, until KTHB updated its access system.
Szilárd Páll was one of these users, and he kindly shared an update to the trick (the one shown above) after consultation with the KTHB tech support. This update is likely to survive longer due to following KTHB recommendations!
