As you read, you'll come across references to other work that can inform your presentation. Looking a promising title up using the citation information is a great strategy.

Let's say you're interested in the 2nd article on this references list.

Google Scholar is good for this kind of search and so is the Library Articles & Books Search.

Search by title: Enter the title of the article you want to find in quotes, e.g., "Relationships between climate and macroscale area burned in the western United States." 

Search by author: Enter the names of the authors of the article, e.g., Abatzoglou and Kolden.
(Sometimes those authors will have co-written many papers together. If that's the case, chances are good more than one of those articles might be relevant.)
