   The Earley citation reference under the title "Generating productions   
   from BNF" by Knuth was for a preliminary report; the title appears to   
   have become "Generating a Recognizer for a BNF Grammar" in 1965. Only   
   the cover pages are available online; however, if CMU could be   
   persuaded to open Box 33 of the Allen Newell collection, you'll find   
   it there.
