That's a very frightened moppet, Grover, using the second person point of view in The Monster at the End of This Book. Kids' books often address the reader using second person. It's useful if you're telling someone how to do something - maybe it's an advice column or a how-to guide.
Again, this isn't a style you'll see in academic writing. In fact, it's really not seen very often.
Third Person
You know what is common? Our final point of view: third person. This is where the narrator doesn't refer to him or herself - as in first person - and isn't addressing the reader - as in second person. Instead, you get an observer's perspective and lots of 'she,' 'he,' 'her,' 'his,' 'their' and 'theirs.'
If first person is someone telling you his or her story, and second person is you being told how you should do something, then third person is more like a camera recording events. That's not to say it's necessarily an objective point of view. A third person narrator can be highly subjective. The narrator just doesn't directly inject him or herself into the story by using 'I.'
There are myriad examples of third person point of view in literature. Here's one, the opening of Jane Austen's Pride and Prejudice: 'It is a truth universally acknowledged, that a single man in possession of a good fortune, must be in want of a wife.' Note that the narrator doesn't say, 'I want a wife' or 'you want a wife.' No, the narrator is not a character in the story.
Aside from fiction, third person point of view is used in biographical works. This is someone telling someone else's story. I wouldn't write, 'And then I was elected as the first President of the United States.' Nor would I write, 'And then you were elected...' I'd write, 'And then George Washington was elected...' That's third person.
This is also the most common point of view in academic writing. It's considered the most formal, impartial point of view. Though, again, it's not inherently impartial. It just seems more unbiased if you don't talk about yourself.
Using and Identifying
For your own writing, it's critical that you're consistent with your point of view within a work. In Moby Dick, if Ishmael stopped narrating the story, it would be jarring.
Likewise, what if we rewrote the opening of Ernest Hemingway's The Old Man and the Sea to shift point of view. It starts: 'He was an old man who fished alone in a skiff in the Gulf Stream and you had gone 84 days now without taking a fish. In the first 40 days a boy had been with me.' Wait, what? It's confusing, right? That 'you' should be 'he,' and that 'me' should be 'him.'
As for identifying point of view, it's important to note that first and second person works can contain third person pronouns. For example, you could say, 'I bought him a biscuit.' That 'him' doesn't make it third person. But third person works will usually only contain 'I' or 'you' in dialogue or quotations.
Focus on the narration, and the pronouns will guide you. If there's any 'I,' 'me' or 'mine,' then it's first person. If there's any 'you' or 'yours,' it's second person. There's no 'I' or 'you' in third person. There's just 'he,' 'her,' 'his,' 'hers' and 'their.' Well, ok, technically there is an 'I' in third person, but it's a little 'I.'
Lesson Summary
In summary, we defined point of view as the perspective from which a work is written. We looked at the three types of point of view: first person, second person and third person.
First person, which uses 'I,' 'me' and 'mine,' is common in fiction and autobiographical works, like personal essays. Second person, which uses 'you' and 'yours,' is not common in fiction. You'll find it in how-to guides and works addressing the reader directly. Finally, third person, which uses 'he,' 'her,' 'his,' 'hers' and 'their,' is common in fiction, biographies and academic writing.
