Besides many illustrated editions of standard works, including in 1842 an edition of the works of William Shakespeare entitled "The Pictorial Shakspere", which had appeared in parts (1838–1841), Knight published a variety of illustrated works, such as "Old England and The Land we Live in" and "The Pictorial Gallery of Arts – Useful Arts", the latter based on the Great Exhibition of 1851. He also undertook the series known as "Weekly Volumes", himself contributing the first volume, a biography of William Caxton. Many famous books, Harriet Martineau's "Tales", Anna Brownell Jameson's "Early Italian Painters" and G. H. Lewes's "Biographical History of Philosophy", appeared for the first time in this series.
