In this section you’ll find information and guidance on literature searching. To find out more about subject specific databases, see the relevant Subject Guide on the Library Gateway.
Planning your literature search
As you begin your search should consider:
Your first searches will most likely be for specific items– for example, an article in the bibliography of a book you read as part of your application.
As you read these specific items, you will develop an understanding of your topic. You will identify important authors, concepts, results etc. All of these can form the base for search terms. You can also use search terms based on your research question.
Many databases will have a thesaurus or subject terms. You can use this feature to look for search terms- it can be helpful to check if your search terms match the thesaurus, and the thesaurus can also suggest additional search terms.
As you search, take note of the results. If they are not quite what you need- perhaps there are too few results, or you get a lot of irrelevant items- you might need to:
What is citation searching?
Imagine you have identified the classic paper within your area and wish to explore how the field has developed since that paper was published. Citation searching allows you to follow the research trail forward and backwards in time.

Which databases offer citation searching?
Many specialist resources provide access to articles which enable you to:
Citation searching is available in a number of specialist sources. When choosing which source to citation search within you should consider the following points:
We recommend that you find cited by data using Web of Science or Scopus in addition to other sources you have used for subject searches.
You can find out about forthcoming conferences in your subject by using:
Web of Science, a large multidisciplinary database, indexes conferences as well as other material – use the conference field in the search boxes. Some subject databases also index conference papers. Have a look at the Subject Guide in your area for more information on what the databases cover.
You can also try the Directory of Published Papers (DoPP).
Doctoral and research Masters theses have been through a comprehensive review process to ensure their quality, and are often quoted in academic work. Undergraduate and taught Masters theses will not include marks (for confidentiality reasons) and it can be difficult to judge their quality.
SHURA (Sheffield Hallam University Research Archive) provides electronic access to SHU Doctoral theses.
You can use the resources below to find doctoral theses from other institutions:
You can search the library catalogues of universities in other countries to find details of the theses produced by their students. If there is a postgraduate thesis you need, and it is not available electronically, the Library’s Document Supply Service will try to obtain it.
The following sources may help you to find theses & dissertations in progress:
Other places to look for information
For example you may have found a number of results matching a keyword search. You could analyse the results to find:
This can help you to identify:
Looking beyond the results of your search
When you have searched a database you will be able to look at your list of results. You can also use database / article page prompts to locate additional content that may match your search or research interest. These are often described as:
Having found your sources, you need to select those you want to read. You should have a set of criteria to help make these choices – these could be very detailed if your literature review is part of a systematic review. The criteria will vary from project to project, but common criteria are:
Corrections
Corrections are an important part of ensuring the body of information is reliable and are often included by the publishers of articles where it is thought these are necessary. If you find an article of interest, it can also be helpful to look out for:
Retractions
In some cases, the issues with an article may be of a magnitude that requires it to be retracted by the authors or by the journal editor. The types of issues which cause retractions range from honest errors to misconduct such a plagiarism or fabrication. When a retraction occurs the article is NOT removed from the journal in print or online. The publisher will usually alert you to the fact that an article has been retracted, however this appears in different ways in different journals and library databases. Look out for notes and watermarks identifying retracted articles.
Retraction Watch is a blog following retractions. It can be a good way of keeping up to date with retractions and an interesting read for researchers.
Requesting resources
We welcome suggestions for new books for library stock.
Document Supply Services may be able to obtain books, journal articles, conference papers, and other items for you via Inter Library Loan from the British Library.
Using other libraries
You may also be able to access the resource at another library. Reciprocal borrowing agreements give you access to many other public and academic libraries.
