Supplemental content may be provided to users that is associated with printed content found in printed publications. Via, for example, a client computing platform a user may provide information identifying a specific publication, and then a content image (or images) representing the printed content. The content represented in the content image may be identified. This technique for identifying printed content may facilitate identification of printed content without requiring a machine-readable marker being included in the pages of the printed publication. Based on the identification of the specific printed content, supplemental content associated with the identified content may be accessed via the client computing platform.
