I want to know the answer to the following question:
What work was the first to see McKerrow use his new method?
All the background I'm provided with is that "He therefore concluded that the correct procedure would be "produced by using the earliest "good" print as copy-text and inserting into it, from the first edition which contains them, such corrections as appear to us to be derived from the author."". Is that enough to answer the question?
Answer: no
