This page looks at how to do a systematic literature search.
You may be conducting a literature search to justify a proposed study, to uncover patterns of findings in the field, to enter into academic debate or to discover gaps in the current knowledge that may lead to future research.
Remember that not everyone would describe your subject in the same words as you would use.
Truncation, OR and AND are the most useful ways of combining terms to retrieve the results you want from a database. Phrase searching can also be useful. Although databases vary slightly in how they apply these can be used in most literature databases.
Truncation replaces the end of a word with a symbol such as * to pick up variant endings.
OR allows you to include synonyms or related ideas in a search.
AND allows you to combine two ideas in a search, narrowing it down.
Phrase searching allows you to search for a group of words exactly as you type them. Many databases do this by putting a phrase in quotation marks.
Are there any limits you can apply to your search to cut down the number of results you have to scan? Common limits are:
You will need to access a wide range of relevant databases and sources of information. It is worth remembering that there are specialist databases for particular types of literature such as conferences and theses.
See the Subject Information pages for links to all subscription databases available via the library for your subject area. The following may also help: Finding Journal Articles; Finding Official Publications; Finding Theses (Index to Theses guide, Digital Dissertations guide).
Database guides are available in the Help & Guides section of the ISS web pages. Most databases also have online help which will show you how to construct a search statement, apply limits, etc. in that particular database. If you have problems using any of our databases contact your subject team or ask for help at the Information Desk in the Library & Information Centre.
Once you have carried out your search you will probably have a large number of results & you will need to evaluate them to decide which to read. Some points to think about are:
You may need to consult other library collections. Other Library Catalogues gives links to local, national and worldwide academic collection catalogues. There are local agreements and national schemes in place which allow physical access to other library collections - see Visiting Other Libraries for more information.
Our bibliographic referencing pages give advice on recording references accurately and consistently. You may want to consider using EndNote reference management software to build up a database of your references. Your subject librarian can give advice about referencing and EndNote.
