Your dissertation is a substantial piece of written work that ideally should conform to a number of academic conventions. One of the most important of these academic conventions is the literature review. In short, the literature review is a discussion or 'review' of secondary literature that is of general and central relevance to the particular area under investigation.

When you have divided your literature review into general works and works of central importance, you should also further divide the literature into sub-categories. By further dividing your literature in this way, you are adding more organisation into your literature review by providing specific sub-categories of relevant literature.
For example in the general works section of your literature review, you might want one sub-heading on the main theoretical debates, one on empirical studies and maybe one on policy. With reference to the more central literature, you could organise this more important reading in a similar way. For example, if relevant, you could have a section on competing theoretical perspectives; a section on the main findings of important empirical studies; a section on policy implementation and its impacts. See the table below.
It will be clear that some of the reading you have done is of more relevance than others. It is important, however, that you do not discard the less relevant work; instead this can form the broad background of your discussion of the more relevant literature within your field. For example you may mention different authors that have dealt with a question related to your field but may not be central to it. Highlight these in broad terms, state how these works have impacted on your particular area. You need not go into great detail about these more general works, but by highlighting these works you are demonstrating your awareness of the scope and limits of your study and how it touches upon other areas of study.
Once you have generated a large number of notes around your reading you might start to feel overwhelmed by the literature. In terms of the organisation and presentation of your literature review, it is worth dividing your review into two main areas: general reading and literature that is of central importance. You will also need to further divide the literature into specific areas relevant to your study for e.g. theories and concepts; policy analysis; empirical studies and so-on. What follows are some general guidelines on how you might do this.
Insofar as the preparation of the dissertation is a process of investigation and discovery, the precise scope of your study may well only emerge as you become closely involved in a detailed review of the literature. At this early stage, your title may be a provisional one that you will revise later. Your dissertation supervisor may advise on the title in order to help you find and define the focus of the dissertation.
You should examine articles in scholarly journals for examples of appropriate titles for a study of this length.
Supervisors have different ways of working and you will, to some degree, need to negotiate your approach to supervision style. For example, your supervisor may advise you to write a short proposal or abstract, say of about 300 words, in which you set out as clearly as possible what you intend to do in the dissertation. The value of this exercise is that it requires you to focus and articulate your thinking. It may be that you will be able to summarise the exact nature and scope of your study, in which case the proposal can serve as guide to refer to as you write the main chapters of the work. Alternatively, it may make you aware of gaps in your knowledge and understanding, and show you the areas that need further thought and research.
It is useful, therefore, to write the proposal and to retain it for reference and revision. It helps to attempt such an abstract even if your supervisor has not suggested that you write one. However, practice varies, and your supervisor will advise you on how to proceed. As you continue to write the main chapters of the work, you may find that your initial plan has changed. This means that when you have completed the chapters that form the main body of your dissertation you can return to the proposal and revise it as much as you need, to form the introduction.
Usually, this comes immediately after the introductory chapter. This may be more than one chapter, but should certainly be written in sections. This should include previous work done on the field of study and anything that you consider to be relevant to the hypothesis or research question and to its investigation. It will include a large number of references to the literature in your chosen area.
The first chapter of the dissertation is the dissertation introduction. The dissertation introduction details the purpose of the study, the research problem, offers a justification for the study and defines the research objectives.
Once you have produced the proposal and discussed it with your supervisor, you may want to write the first draft of a chapter of the dissertation. When you hand in this draft, you should arrange a tutorial to receive your supervisor's verbal or written comments and suggestions on how it may be improved. You may, for example, produce a draft introduction setting out the issue, together with a literature review which covers what, if any, treatment of the topic has gone beforehand. You may also wish to draft those sections of the methodology chapter that cover the methods that you wish to use, together with a justification for why you think those methods are best.
The Background Subsection
The Background sub-section to your dissertation introduction should place your research area in context, referring to relevant literature sources using a variety of direct and indirect referencing techniques.
Overall Aim & Individual Research Objectives
The Overall Aim and Individual Research Objectives sub-section of your dissertation introduction clarifies your research focus in simple terms, where your main research aim is identified and the specific research objectives needed to complete your main aim are enumerated. Both your overall aim and your individual research objectives can be transformed into research questions. In this sub-section provide an overview of the research methods that you will use to do your research and remember to estimate the length of time to complete your major research tasks.
