The advance in technologies for publishing digital scholarship has outpaced the development of technologies for reliably preserving it. Authors and publishers are creating increasingly sophisticated products without realizing that some of their enhancement choices might put preservability--and valuable scholarship--at risk. The poster describes the in-progress work and findings of a collaboration between preservation organizations, libraries, and publishers that are creating enhanced digital publications. The work aims to identify what can be effectively preserved with existing technologies, and to produce a recommended set of practices to help authors and publishers prioritize and plan their enhanced digital products for maximum preservability.
