Decolonising Literature Searching

Highly Sensitive Searching Strategies  (Or HSSS) are a way of searching academic databases that reduce the risk of missing key papers. This is very important as countries outside of UK/US and European academia may be considered to have a disadvantage in publishing in journals. Metadata and keywords may not be as extensive or missing and a good 'Highly Sensitive Search Strategy' may help to reduce this risk, but certainly will not eliminate it. Searching through the additional Global and Local scholarly journal websites and databases (below)  is strongly recommended,

Guidance on a good 'Highly Sensitive Search' can be found on the Systematic Review Libguide

About Search Filters

Even the best search can be improved by reviewing previous search strategies and filters. Cochrane Effective Practice and Organisation of Care (EPOC) group has published a list of LMIC filters for databases searching. (Unfortunately the EPOC Group is no longer active, but the latest filters can be downloaded here )

The ISSG Search Filters Resource includes a selection of papers that review search filter performance for Geographic Regions, and include Middle Eastern and LMIC countries.

Also the paper ‘The ScHARR LMIC filter: Adapting a low‐ and middle‐income countries geographic search filter to identify studies on preterm birth prevention and management’,  is a good paper that discusses geographical search filters.

If undertaking a Systematic Review or other evidence synthesis, the Unicef Methodological Briefs on Evidence Synthesis series is recommended reading.

Some of the resources in these guides are 'Pre-Print Databases' Preprints are papers not yet peer-reviewed and published in a journal. Searching these papers can add additional diversity to a literature search. In most cases, these papers can be considered final drafts or working papers

Using Google Scholar is often discouraged as part of a good search strategy, after all, a University can have multiple high-quality 'Native Interfaces' (An interface where you can produce a high-quality search).  Evidence does show that these databases, even the large multidisciplinary products such as Scopus and Web of Science are not 'comprehensive' when examined in a worldwide and decolonised approch.

In the paper Recalibrating the scope of scholarly publishing: A modest step in a vast decolonization process open access journals using OJS (Open Journal Systems) are poorly represented in Scopus, Web of Science, and EBSCOhost,1649, 279, and 771 respectively, while Google Scholar indexes 22,679. 

The OJS publishing platform is extensively used by authors in the Global South, due to its low cost of entry, as detailed in Beyond Web of Science and Scopus there is already an open bibliodiverse world of research – We ignore it at our peril. Therefore the recommendation would be to add a Scholar search to any strategy that benefits from Decolonisation.

One of the common reasons for excluding Google Scholar is to minimise the retrieval of studies published in predatory journals and ensure the validity of the search. However the concept of a 'predatory journal' may in itself be biased and worthy of future research. A recommendation would be to consider additional steps such as critical appraisal, reviewing citations and references, or validity checking of the data rather than artificially limiting your search.  (See How should we handle predatory journals in evidence synthesis?

Trip Pro is a worldwide clinical search engine designed to allow users to quickly and easily find and use high-quality research evidence to support their practice and/or care with a strong focus on highlighting evidence-based resources. Trip searches PubMed, National and International guidelines, systematic reviews, clinical trials databases, blogs, leaflets, primary research and much more. Filters can be used to focus on LMIC policies and research. Access at the Database A-Z

Lens.org serves over 200 million scholarly records, compiled from Microsoft Academic, PubMed, and Crossref, enhanced with OpenAlex and UnPaywall open-access information. It therefore both surfaces in searches, and allows access to large numbers of Open Access journals, and therefore the academic output of the Global South.

You can search using Keywords, Titles, and Abstracts similar to a Scopus or Web of Science search.

You can exclude certain regional groupings such as G7 and BRICS countries, or choose to only search those countries, along with the more common country-level filters.

OpenDOAR, or the Directory of Open Access Repositories, is a resource for accessing listings of free Open Access journals by individual countries. The repositories are assessed by OpenDOAR staff to ensure they meet quality standards with less risk of 'predatory' journals.
