Multi-Spectral Imaging at Newman Portal

The digitization lab at Washington University in St. Louis currently has access to a multi-spectral imaging system that we are making available to interested researchers. This technology allows for the recovery of obscured or illegible text in historical documents, which are scanned under lighting of varying wavelengths. Open access software (Hoku) is used to analyze the captured data. We've identified a copy of Frank Stewart's History of the First United States Mint (1924), which bears an effaced inscription, for our initial testing.
