Before you can start adding your references to Reading Lists Online, you need to install a bookmarklet tool on your browser. The instructions vary depending on the internet browser you want to use. You only have to install the bookmarklet tool once on your PC or your laptop. Usually, this is simply a matter of 'drag and drop' into your browser bookmarks bar.
There is a video on how to add the bookmarklet to Google Chrome below - other browsers will be added soon
