Systems and methods are provided for previewing audio data associated with an audio book or other item. In some embodiments, following capture by a mobile computing device of an image of a graphical code included on packaging associated with an audio book, a request may be received from the mobile computing device for audio data and/or other data associated with the audio book. The request may include a uniform resource identifier generated using the graphical code from the image captured by the mobile computing device. In response to receiving the request, audio data associated with the audio book may be retrieved from a data store. The retrieved audio data may then be sent to the mobile computing device for playback by the mobile computing device.
