Many of his science fiction stories are of satirical and humorous character. Lem's books have been translated into over 40 languages and have sold over 45 million copies. Worldwide, he is best known as the author of the 1961 novel "Solaris", which has been made into a feature film three times. In 1976 Theodore Sturgeon wrote that Lem was the most widely read science fiction writer in the world.

His essays and philosophical books cover these and many other topics.
