Question: The bibliographer Ronald B. McKerrow introduced the term copy-text in his 1904 edition of the works of Thomas Nashe, defining it as "the text used in each particular case as the basis of mine." McKerrow was aware of the limitations of the stemmatic method, and believed it was more prudent to choose one particular text that was thought to be particularly reliable, and then to emend it only where the text was obviously corrupt. The French critic Joseph Bedier likewise became disenchanted with the stemmatic method, and concluded that the editor should choose the best available text, and emend it as little as possible.
Is there an answer to this question: What was the initial definition of copy-text?

Answer:
the text used in each particular case as the basis of mine
