Kortext requires the Google Chrome browser and the default browser in RAS is currently IE. To workaround this, instead of clicking in the Library Search icon (which is internet Explorer) once in RAS, click on the + symbol to the left of the RAS home screen, which opens a menu.
Select 'Communications browsers' and select Google Chrome.
This then opens a Chrome session, and if you navigate to the Library homepage / Library Search, and search for the title as normal, access is granted on the Kortext platform.
Please contact Library Help and alert us to the problem, and we can provide more guidance from there.
