Generating a Cover for a Section of a Digital Magazine

A digital magazine application executing on a client device presents a digital magazine to a user including content items retrieved from one or more sources based on information associated with the user. When presenting the digital magazine, a cover is presented including an image and one or more headlines describing one or more content items included in the digital magazine. The cover may be generated by clustering content items included in the digital magazine and ranking content items in various clusters based on their characteristics. Based on the rankings, information describing content items from various clusters is included on the cover. Alternatively, the cover includes information describing content items identified based on the order in which the content items are presented by the digital magazine.
