The 'Kim' book series by Rudyard Kipling is a classic that has captivated readers for generations. Initially, the story of Kimball O'Hara was published as a single novel titled 'Kim' in 1901. However, due to its popularity, it has been reprinted and compiled into various editions, sometimes split into multiple volumes for easier reading or as part of collected works.
Some editions, especially those aimed at younger readers or educational purposes, might divide the novel into two or three volumes with annotations or illustrations. But traditionally, 'Kim' stands alone as a complete novel. If you're looking for a multi-volume experience, you might explore adaptations or companion books that expand on Kipling's world, but the original work remains a singular masterpiece of adventure and espionage set in colonial India.
