1. 18 September 20151 The Literature Review What literature and where?

2. 18 September 20152 What is a literature review? In the terms of a literature review, "the literature" means the works you consult in order to understand and investigate your research problem.

3. 18 September 20153 What literature should you review? 1. Journal articles: these are good, especially for up-to-date information. They are frequently used in literature reviews because they offer a relatively concise, up-to-date format for research. Depending on the publication, these materials may be refereed or non-refereed materials.

4. 18 September 20154 What are refereed journals? Refereed materials are publications reviewed by "expert readers" or referees before publication. Refereed materials are also referred to as Peer Reviewed. Refereed materials assure readers that the information conveyed is reliable and timely.

5. 18 September 20155 What about non-refereed journals? Non-refereed materials such as Trade Journals or Magazines use less rigorous standards of screening prior to publication. Non-refereed materials may not by checked as intensely as refereed materials, but many can still be considered scholarly.

6. 18 September 20156 What literature should you review? 2. Books: remember that books tend to be less up-to-date, as it takes longer for a book to be published than for a journal article. They are still likely to be useful for including in your literature review as they offer a good starting point from which to find more detailed and up-to-date sources of information.

7. 18 September 20157 What literature should you review? 3. Conference proceedings: these can be useful in providing the latest research, or research that has not been published. They are also helpful in providing information about people in different research areas, and so can be helpful in tracking down other work by the same researchers.

8. 18 September 20158 What literature should you review? 4. Government/corporate reports: many government departments and corporations commission or carry out research. Their published findings can provide a useful source of information, depending on your field of study.

9. 18 September 20159 What literature should you review? 5. Newspapers: since newspapers are generally intended for a general (not specialised) audience, the information they provide will be of very limited use for your literature review. Newspapers are more helpful as providers of information about recent trends, discoveries or changes, e.g. announcing changes in government policy. Newspapers do not give unbiased opinions.

10. 18 September 201510 What literature should you review? 6. Theses and dissertations: these can be useful sources of information. However there are disadvantages: they can be difficult to obtain since they are not published, but are generally only available from the library or interlibrary loan the student who carried out the research may not be an experienced researcher and therefore you might have to treat their findings with more caution than published research.

11. 18 September 201511 What literature should you review? 7. Internet: the fastest-growing source of information is on the Internet. bear in mind that anyone can post information on the Internet so the quality may not be reliable the information you find may be intended for a general audience and so not be suitable for inclusion in your literature review (information for a general audience is usually less detailed)

12. 18 September 201512 Why write a review? The literature review is a critical look at the existing research that is significant to your project. You should evaluate what has already been done, show the relationships between different work, and show how it relates to your project. It is not supposed to be just a summary of other people's work.

13. 18 September 201513 What sort of questions should the review answer? What do we already know in the area concerned? What are the existing theories? Are there any inconsistencies or other shortcomings? What views need to be (further) tested? What evidence is lacking, inconclusive, contradictory or too limited? Why study (further) the research problem?

24. 18 September 201524 Secondary Sources Is a summary or description of research study written by someone other than the study investigator/s.
