When we consider point of view in literature, there are there main types that are utilised. Firstly, we have first person narration, where the story is told from the point of view of one character in the story who forms part of the action. This is easy to spot because the first person is used, "I." Secondly, we have the omniscient narrator, that is a god-like narrator who does not form part of the action but looks down upon all the characters and can see into their thoughts and minds. This can be identified through the use of the third person, "he" and "she," but also through the way that the narrator focuses on a number of different characters. Lastly, the third person limited narrator is again written in the third person, but the narrator chooses to limit him/herself to telling the story from the perspective of one character alone, and follows this character around during the course of the story. We only get to see the thoughts, feelings and motives of this one character, though we can see other characters through their eyes.
When we consider these three choices, it is clear that this excellent novel is written using the third person limited point of view. This can be shown by the way that the narrator, who writes in the third person, and is separate from the story, chooses to follow Winston Smith around. We never leave him, and he is the only character whose thoughts and motives are revealed to us.
