Literature Reviews are an important part of academic work providing an overview and analysis of a research question or topic. You may be asked to write one for your dissertation, project or essay assignment.
A good Literature Review should put your research into context, demonstrating how it relates to wider research in your subject area. The Literature Review should show a clear understanding and knowledge of your chosen topic, include relevant current research and key authors, and identify any areas in the literature that support need for further research.
For Literature Reviews and Essays and Assignments you will usually be asked to focus on academic and peer-reviewed sources, like textbooks, journal articles, research reports and conference proceedings. You can find these from the Library’s Electronic and Print collections.
Using Search Techniques allows you to build your search to expand or focus your results.
Placing your keywords, two words or more into “double quotation marks”, creates a phrase search. This can be used to focus your results to more relevant results, especially if search has generated numerous results.
“Formative Assessment” “Strategic Management”
Tip! This is used in most databases, but Scopus uses {curly brackets} for exact phrase - {Health Promotion}
Truncation is useful if you want to include variations of a keyword, it allows you to simultaneously search for various word endings. Search using the stem of a word and an Asterisk * for example, therap* to find therapy, therapies, therapist, therapeutic.
Wildcards are useful to searching for with various spellings – which is usually a question mark ? to substitute a letter of a word. For example, “organi?ation” will give you “organisation” and “organization” in the search results.
Tip! Different databases use different symbols, check before searching.
To create an effective search, you need to combine your keywords together into a string, linking them together to construct your search. You can link the keywords using Boolean Operators AND, OR, NOT to construct string to expand or narrow your results. They are used in Capital letters as they are instructions to the database as to how you want the keywords to be searched for.
AND - Use AND to focus your search, an AND search returns both keywords in the results, for example, students AND “Higher Education”.
OR - Use OR to widen your search, using OR search returns either keywords in the results, for example, university OR education.
NOT - Use NOT to exclude keywords from your results, for example, “South Wales” NOT Australia.
This can help remove non-relevant results, but always use it at the end of the search string. Using NOT can filter out some useful results so it may be for some searches you add additional Keywords to focus the results instead.
