When researching the literature - or evidence - on a topic as part of an assignment, you will often be expected to compile a search strategy (keywords used, resources selected, criteria applied), apply this consistently then summarise these actions, with justifications, as a separate section of your submission.
The 'Literature Review' tab on the Dissertation Support guide provides questions to help you compile your search strategy.
The Library also has textbooks which can advise further. For example:
If the article, or book, is not available, see possible External and Open Access options.
Still no success?
Library staff may be able to obtain a copy for you - see our Inter Library Loan guide for details.
