Library catalogue downtime

You may recall we had some problems with the library catalogue last semester. The problems were due to some subtle incompatibilities between the latest version of the library catalogue and our self-issue stations. We solved the problems by uninstalling the latest version of the library catalogue and reverting back to a previous version. In the interim the boffins at Heritage (our library management system suppliers) have been working away and now think they have solved the problem. Hence, this afternoon, from 2pm onwards, the library catalogue will be down as we attempt tp upgrade to the latest version again. Hopefully it shouldn't be down too long.
