By assigning the subjects "Communication history" and "Mass media history" to your search, you ensure your results will be about your course topic. Use the second search bar to add one of the assigned media types: books, newspapers, magazines, radio, sound recording, film, television and the internet. You might also try the search without the term "history".

You can refine your search further by using the filters for Resource Type. This will isolate the various types of sources required in your assignment. Use the additional filters for showing specific topics, peer-reviewed articles, or items available online. Also consider limiting pub lication dates next to the search bars to isolate more recent items.
