Currently, much of Polish science fiction and fantasy resembles that familiar to English-language writers. There are many science fiction writers as well as fantasy writers in Poland, and their works vary from alternate histories to hard science fiction. The best internationally known Polish science fiction writer is undoubtedly Stanisław Lem, although many others can be considered world-class, with their books being translated into many (mostly European) languages. Relatively little Polish language science fiction and fantasy has been translated into English, even though countless English language writers have been translated into Polish.
