Literature review is an essential part of any proper research (and not only) project: it basically answers the simple question of “what is the history of the subject of my project, and what is the current state-of-the-art?”. It aims at helping you understand what are the pitfalls you should avoid, and what are the opportunities for improvement. Through literature review you are researching what others have done in the domain you are working so that you can get inspired about how to work for your own projects. It also helps you build the appropriate language and terminology, so that you can search things more efficiently.
