Update 19/3/2017. We have upgraded the site and the mobile issue is solved. Thanks for your patience.
This website will need to be updated in order to play nicely with mobile devices, once that happens all should be fine.
However, due to incredibly boring technical reasons it may be a few more weeks before we are able to upgrade the website to a mobile friendly version. Till then, the website and especially the Digital Library are best enjoyed on a laptop or desktop PC/Mac (rule of thumb: if it’s got a proper keyboard it should get along nicely with the website).
