The following script does essentially two things: it searches 33586 lines of the Erdman text as one long string, correlates the line number associated with a hit with the source information extracted from the 33586 lines from another file, and prints that with each hit, plus 37 characters before and after. Kludgy as it is, this format enables search capabilities that exceed those of the hierarchy-bound, heavily marked up Blake Archive version ('search' at bottom).
