Cohen, in an obituary for Kittel in 2019, remarked that the original book "was not only the dominant text for teaching in the field, it was on the bookshelf of researchers in academia and industry throughout the world", though they did not provide any time frame on when it may have been surpassed as the dominant text. They also noted that Kittel's content choices played a large role in defining the field of solid-state physics.
