[Don Richard] Cox has divided the material on literary criticism and analysis into two sections — one from 1871 to 1939, the other from 1940 to 1997. This division, Cox explains in his preface, “reflect[s] the generally acknowledged shift in Dickens studies that comes with Edmund Wilson’s  article, “Dickens: The Two Scrooges”. Before the publication of Wilson’s article, Cox reminds us, the focus of most scholarship and debate was on finding a solution to the “mystery”. Cox asserts that Wilson’s article goes beyond this narrow focus and “stresses the importance of this novel to our understanding of Dickens and his work”. Furthermore, Cox uses this division in dates to emphasize another major change in Dickens scholarship — “the changing of the guard” that inevitably occurred as foremost scholars of the earlier era passed away, and new scholars with new insights came to the forefront.
