View the Vitae Researcher Development Framework (RDF) provides support and resources for “personal, professional and career development of doctoral researchers and research staff in higher education institutions and research institutes”.

In areas of information literacy,  Vitae includes support to develop your information search skills via the Informed Researcher Booklet and Information Literacy Lens on the Vitae Researcher Development Framework. There are additional publications available as well as other views of the Vitae Researcher Development Framework

When using databases to search for systematic reviews:

(1) Medline – OVID (EBM Reviews – Cochrane Database of Systematic Reviews 2005 to November 23, 2016)

  • For example: Type the search sentence – respiratory distress in neonates
  • Select the systematic review title: Positive end expiratory pressure for preterm infants requiring conventional mechanical ventilation for respiratory distress syndrome or bronchopulmonary dysplasia.
  • Read and review

(2) Cochrane Library and Cochrane Clinical Answers

Have u heard of using a Logic Grid to perform your search? Watch this video on how you can do this using Embase

ResearcherID provides a solution to the author ambiguity problem within the scholarly research community. Each member is assigned a unique identifier to enable researchers to manage their publication lists, track their times cited counts and h-index, identify potential collaborators and avoid author misidentification. In addition, your ResearcherID information integrates with the Web of Science and is ORCID compliant, allowing you to claim and showcase your publications from a single one account. Search the registry to find collaborators, review publication lists and explore how research is used around the world! (Source:

Recommended Sources

There are a number of sources where grey literature can be found. These include:

  • View the Digital Repository (DR-NTU) open access contributed by researchers from LKCMedicine and other communities. These are final peer-reviewed manuscript of journal articles and conference papers.
  • View the Digital Repository (DR-NTU) restricted access contributed by students from LKCMedicine and other communities. These are full-text versions of theses or reports.
  • WorldCat which indexes millions of holdings from numerous libraries world-wide

The Internet is now a major source to retrieve grey literature and often a good starting point to research a particular topic area.

Evaluation tools for…

  • Grey literature materials using the AACODS technique to enable evaluation and critical appraisal
    • Authority: Is the author credible?
    • Accuracy: Is it supported by documented and authoritative references? Is there a clearly stated methodology? Is it ‘in line’ with other work on the same topic
    • Coverage: Have limitations been imposed and are these stated clearly?
    • Objectivity: Can bias be detected?
    • Date: Can’t find the date? Rule of the thumb is to avoid such material
    • Significance: Is it relevant? Would it enrich or have an impact on your research?
