In conjunction with the Distance Learning Office, the University Library provides a very useful Guide to the Library for distance students, which is updated annually. As well as some useful information about making use of resources, the Guide contains the information you will need to help you find your way around the Library.
Contact the Distance Learning Office to ask for the web link that will take you to this useful document:
Email distance.learning@otago.ac.nz
Once you receive the link, be sure to bookmark it, so that you have it handy when you need it.
And remember, feel free to contact the Library staff if you can't find what you're looking for!
