Psychology: DClin systematic literature searching: 6. Managing your search results

This tutorial will guide you through the steps required to systematically search for literature for your service-related project and thesis.

APA referencing

Every time you get results from a database (or another source), you will need to record and manage them. This needs to happen before you can de-duplicate your results and go on to appraise and analyze them.There are a number of tools and techniques available to help you navigate this process.

Managing results

Most databases allow you to create a personal account providing you with an area where you can save your searches, and sort and export your search results. If you alter your original search, you can save the new search and track the changes.

The help section within a database provides advice on how to create an account (please note you will only need to create one account for each platform i.e. Ovid or EBSCO). You should use your university email to register.  

It is recommended that you conduct your searches in individual databases. A good search is likely to find some of the same relevant results in all your searches. Therefore, you will need to de-duplicate your results (don't forget to record your results total before de-duplication). 

You can do this process in referencing software (remember to back up your library first) or using Microsoft Excel or other spreadsheet software by collating all your results, filtering and looking for the duplicates. You will need to record the number of references removed and the total remaining after de-duplication.

De-duplication in Endnote

EndNote will search the currently selected references for duplicates. To search the whole EndNote Library, click on the All References folder.

  • Go to the Library menu and select Find Duplicates.
  • Compare duplicate references to decide which to keep. The display automatically highlights any differences it has detected between the references, if any. You can copy and paste information between references if necessary.
  • If you select Keep this record the other record will be sent to Trash.
  • If you want to keep both records, or decide later, click on Skip to go to the next duplicate.

One of the most commonly used reporting tools is PRISMA. The PRISMA flow diagram charts the flow of information through the different phases of your systematic search. It maps out the number of records identified, included and excluded, and the reasons for exclusions.

You will need to document your searches in sufficient detail to allow others to be able to reproduce and assess the thoroughness of the search. You will need to keep track of: 

  • Databased searched, the platform used e.g. OVID Medline or Medline (PubMed), search option e.g. multi field or advanced, and
  • The date each search was conducted
  • Subject headings and keywords used including 
  • Search history including the combination of terms
  • Numbers of results retrieved for each search and combination 
  • Total number of records
  • Duplicates identified 
  • Numbers pre and post screening

These details will help you complete your PRISMA diagrams. 

Referencing software

There are various software packages that you can use to help compile and manage your references into your own personal database or library. They allow you to import your references directly into your own database from many online sources such as bibliographic databases, electronic journals and library catalogues. They also allow you to work in conjunction with a word processing package to insert in-text citations, your footnotes and bibliography into a document and then automatically format to your preferred style. 

Endnote, Endnote Web, Mendeley and Zotero are popular options. Some packages are free, some you need to pay for. Endnote is available via the university for personal devices. It is worth spending some time to decide which one best meets your needs. 

Microsoft Word also offers a basic referencing function: if you decide to use this, you will need to check that the references it produces match the formats required by the University of Exeter styles described in this guide.

Finding full text

Sometimes you may know the articles you are looking for but can't find / access the full text. This guide will help you check if the university provides access through our resources. If not, you can use this service to try to obtain access.

Systematic review specific tools

The university does not have an institutional subscription to any specialist systematic review tools such as Rayyan or Covidence.
