We propose the "Digital-Surrogate Seal of Approval" (DSSOA) as a simple way of describing digital objects created from printed books and other non-digital originals as surrogates for the analog original. The DSSOA denotes that a digitization accurately and completely replicates the content and presentation of the original. It can be used to express an intended goal during the planning stages of digitization and to guarantee the quality of existing digital surrogates. The DSSOA Criteria can be used to evaluate individual digital objects or entire completed collections. DSSOA is independent of production technologies and methodologies and focuses instead on the perspective of consumers — including libraries that rely on digital surrogates.
