Update 14.09.16 – Similar problems have been reported with other electronic Library resources, including Ebrary and the Discovery Service. This post has been updated in this replacement post.
Intermittent problems have been experienced by lecturers editing online reading lists. Problems have been reported at different times with all the major browsers, although Firefox appears the least badly affected so far. Information Services have made fixing the problem a priority and expect to resolve the issues by tomorrow afternoon.
In the meantime, all we can suggest is that if you experience problems that you force refresh your web browser, forcing it to look afresh at what you are editing. On Windows computers, this can be done by pressing Ctrl + F5.
