If you choose to study Literature in the US, you will learn how to read different texts and analyze the style, use of different types of language, and meaning, in depth. You will also learn how to write clearly, concisely and analytically in stylistically different forms. Generally, Literature courses are divided into different focuses: British Literature, American Literature, World Literature, and periods (pre-1800 and post-2000). You will have core courses in several of these topics and will also be expected to choose a focus of your own interest, such as creative writing or drama. You will ultimately gain a much more in-depth understanding of the texts you cover than is possible from solo-reading, and learn how to express your knowledge through written analysis and presentation or class discussion.
There are several different paths for careers in literature as a graduate. You can also take graduate courses and become a teacher, lecturer, or journalist, with common crossovers for graduating English students including business, law, and education. Or you can use your analytical skills to move into unexpected careers such as marketing, advertising, or pretty much anything you are willing you adapt to. There are also obvious positions available in the publishing industry, from editor, to proofreader, to literary agent. Many creative writers, including novelists, poets, and screenwriters, among others, start their careers by gaining an in-depth understanding of written English before developing their individual abilities for expression through writing.
