The content we ingest, whether by way of information, communication, or entertainment, is increasingly digital content, appearing as digital media and requiring the mediation of digital devices. The on-going emergence of new digital media and devices is anticipated, making the stability of their organization uncertain, unless we can devise a faceted approach capable of accommodating future developments. The paper presents a complex and hospitable facet analysis for digital media based on the functions of generation, representation, distribution, and use. For digital devices, a simpler facet analysis emerges, with a primary split between general-purpose devices and task-specific devices; the latter set of devices classes with the task. The Dewey Decimal Classification system is used throughout as a case study.
