As well as using academic sources such as books and journals, an important part of evidence-based practice is the ability to link theory and research to practice. These types of sources are sometimes referred to as grey literature, defined by Cochrane as “There are many definitions of grey literature, but it is usually taken to mean literature that is not formally published in sources such as books or journal articles.” Cochrane Handbook v.5 - Part 2, section 6.2.1.8 Grey literature databases.
There are a number of key source types beyond books and journals that you will be expected to use in your assignments and some examples of these are shown below.
Please see the following video which demonstrates how to search for and evaluate these source types effectively, and also see the other tabs in this section for the links to webpages from the video to find these sources as well.
Searching for Grey Literature (video, 57 min)
Some of the common issues when finding and using web-based sources to be aware of are:
What is the author/organisation’s knowledge and expertise on a topic? Are they a trusted and reputable organisation?
Do you trust the information to be accurate and correct? Has your source also used good quality sources and provided references? Is this factual information or opinions?
What are the intentions of the source, are they trying to persuade or sell? Consider any bias and whether they are providing a balanced view or siding with one perspective/viewpoint/argument.
Is the source recent or up to date, has a source been replaced by a newer one? Important for statistics, latest versions of policies/guidelines etc. If there is no date on the source then this would be a concern in terms of knowing how current it is.
If you are searching for these types of sources they will not usually we found in academic source locations like the library catalogue, or academic databases. Instead these sources are usually found on websites and via search engines. Where possible try to identify relevant government departments, organisations, and charities in a particular field and search for publications and information directly on their own websites.

Dissertations and theses of masters and Doctoral work can be useful resources, particularly if the topic you are searching for does not have a lot of research articles published on it. Please see the guidance below on finding these.
Edinburgh Napier:
Search the Edinburgh Napier Research Repository to find recent PhD, DBA and research-based (not taught) Masters theses online.
Hardcopy theses are stored in Merchiston Library, and listed on LibrarySearch.
Other UK institutions:
To find a UK thesis from an institution that is not Edinburgh Napier University, search EThOS - the British Library E-theses Online Service.
If the thesis is not available full-text online from EThOS, there may be a link to the institutional repository.
International institutions:
Proquest has a large collection of US Phd and Masters dissertations and theses, narrow your search down to just this source type.
DART Europe searches etheses repositories from European institutions. Full-text access is available.
