"Digital-Surrogate Seal of Approval" (DSSOA) is a proposed way to describe the accuracy and completeness of digital objects that were created from printed books and other non-digital originals. It indicates that the original has been digitized completely and with 100% accuracy. This seal of approval may be applied to a digitized version of an analog original when it accurately replicates the original. To do this, two criteria must be met and verified:
- Completeness. All pages of the original are fully and completely reproduced.
- Accuracy. The original layout and appearance are preserved. All text is legible and there is no visual degradation when compared to the original.
