The following is a podcast located on the University of Adelaide Library website under the Podcasts tabs. Currently they only have 3 podcasts and the length of the podcasts are all short, yet sweet.

The podcast is called, "Research Librarians and how they can help you" and is read by library staff members Rebecca and Ursula. It details why a research librarian could prove useful in aiding students with their assignments, rather than just doing google searches and getting lost along the way. It is promoting the use of the university library and its staff to the University of Adelaide students.
There is also a transcript of each podcast for clients to read which could prove useful if the they needed to be in a quiet environment or simply did not want to listen to the podcast at the time, or even if they wanted to follow it along with the script for better understanding.
