This guide will help you evaluate web resources.
Literature reviews require you to critically evaluate the literature.
To ‘critically evaluate’ a source is to scrutinise it to determine its strengths and weaknesses. The following REVIEW criteria will help you to critically evaluate your sources:
R is for Relevance
Does the reference completely cover your topic, or only one aspect of it? Have you read widely to determine how relevant it is in relation to other sources?
E is for Expertise of author
What is the educational background of the author? What are their qualifications? Are they writing in their area of expertise? Are they regularly cited by other authors in the field?
V is for Viewpoint of author/organisation
Does the author have any personal or professional affiliations that may bias their work, in other words, do they have any conflicts of interest? Has the research been sponsored by an organisation with a vested interest in the topic? What is the purpose of the source – to inform, persuade or entertain?
I is for Intended audience
Is the reference aimed at the general public or a scholarly audience? Is it intended for professionals in the field or a community of researchers? Is it intended for a large or small readership?
E is for Evidence
Are opinions supported by scholarly evidence? Is a particular referencing style used properly and consistently? Has the reference been subjected to peer review?
W is for When published
Was the reference published recently? Have significant developments been made in the subject area since the reference was published?
Always evaluate the information you read. Be particularly careful when consulting Wikipedia and similar Internet sites as the authority and reliability of the content cannot be guaranteed. Remember to work SMART:
Source - is the source well-known, reliable, up to date?
Motivation - why does this website exist? Are they selling a product? Supporting a particular lobby?
Authority - is the author's name on the page? Is the author well-known in the field?
Review - has the information been reviewed or checked by others working in the field?
Two sources - is the information supported by other reliable sources?
The databases the Unisa Library subscribes to generally index articles that have been peer reviewed by experts in the field before being accepted for publication. These databases also allow you to limit your search to peer reviewed journals only.
