eReadings for various units of study can be located by searching by unit of study code or name or by lecturer name via this link: http://opac.library.usyd.edu.au/search/r which is available on the library homepage under 'Unit of study readings'. If there is a list available you will find it there. Not all lists for all units of study will have been provided to the Library though. If you can't find the list you need, you may need to check with your lecturer to see if they have provided their reading list to the Library.
If you locate the item that you need on a list, simply click on the title to see full details and click on the link that says 'Connect to the full text' or 'Connect to the article via..'. You will then be prompted for your UniKey login and password to view the full text.
