Few authors are as world-renowned as Charles Dickens. From Oliver Twist to A Tale of Two Cities, the 19th-century writer produced some of the most acclaimed novels that are still widely read and studied today. And while his work is now enjoyed in book form, it's not how his stories were appreciated during the Victorian era. Instead, Dickens' works were published in serialized installments, ranging from weekly to monthly. Accompanying his stories were detailed illustrations.
