Enhancements
Erased, faded, and otherwise defective or illegible readings are often enhanced by ultraviolet fluorescence (UV) and digital image processing (DIP).
The search results provide folio and line number, text (or bracketed colons for erased text), and means of enhancement (UV, DIP) with revealed text.

In this case UV reveals an uncial 's' deleted from 153r16. Click the folio at this spot to link to an image with an explanatory note.
