Beloved by children and adults worldwide, the writings of C. S. Lewis have a broad and enduring appeal. Although he is best known for the iconic Chronicles of Narnia series, C. S. Lewis was actually a man of many literary parts. Already well-known as a scholar in the 1930s, he became a famous broadcaster during World War Two and wrote in many genres, including satire (The Screwtape Letters), science fiction (Perelandra), a novel (Till We Have Faces), and many other books on Christian belief, such as Mere Christianity and Miracles. His few sermons remain touchstones of their type. In addition to these, Lewis wrote hundreds of poems and articles on social and cultural issues, many books and articles in his field of literary criticism and history, and thousands of letters.

At Oxford University, he became a charismatic lecturer and conversationalist. Taken together, his writings have engaged and influenced, often very deeply, millions of readers. Now, Lewis societies, television documentaries, movies, radio plays, and theatrical treatments of his work and life have become common, and he is frequently quoted by journalists, critics, and public thinkers.
