When to Use Capital Letters?

Sometimes it is hard to distinguish when it is and is not appropriate to use capital letters. You use them when you are spelling someone’s name, a state or city, any title that goes before a name, and books/movies/plays (except for words such as of, and, or, etc.). For example, it’s Jennifer Hudson, not jennifer hudson. A few more examples: Kentucky, The Wizard of Oz, President Barack Obama, Where Are You Going, Where Have You Been?
