Information is relevant when it helps you to answer your research question. You assess the information on the basis of format, content and degree of up-to-dateness.
Does the information relate to your research question and the aim of your research?
Ask yourself the following questions:
* Does the information answer my research question?
* Are the quality and the level of the information appropriate to my research question and the aim of the research?
If you are conducting academic research into depression, an article from Cosmopolitan or Hello! will not provide information of the standard you require. Articles from academic journals are more appropriate. (See the chapter Choosing information sources)
Which publications are most suitable depends on your information requirement. I.e. if you need current, in-depth information on a topic it is better to consult recent journal articles in stead of a handbook. And in preparation for writing a light-hearted article for Rolling Stone you are probably not going to study a monograph.
The term ‘current’ usually refers to recent events or developments. In order to determine whether information is current, check whether it still reflects the present situation. A book or article that was not written recently may still be current.
Usually current information is required, but not always. The importance of this criterion depends on your research question.
How complete is the information you have found?
Are you sure you haven‘t overlooked any relevant information? Have you considered all points of view? Although being comprehensive is usually not possible and at this stage in your academic career not strictly necessary, you should always try to be as complete as possible in the literature you are using for your research.
This refers to how sure you can be that the information is correct. How credible is the information? How objective is the information? There are several aspects to take into consideration when you are assessing how reliable your information is. These aspects relate to the origin of the information as well as its quality.
* What do you know about the author? Is he an authority on the subject? Is he a recognized author in his subject area? Has he been cited by others? Which organization does he work for?
* What do you know about the organization? Publications by well-known and respected organizations are generally more reliable than material published by vague charitable foundations with dubious or unclear objectives.
* Does the author or organization receive funding from sponsors? Sponsorship is not necessarily a problem, but be aware of any commercial interests that may be involved.
* Is the quality of the publication assessed? If so, is this done by editors? Are articles peer reviewed? Peer-reviewed articles are very reliable because they have been critically assessed by more than one expert/academic.
* Are the supposedly factual descriptions correct? Check whether they are backed up by information in other sources.
* Are opinions supported by facts?
* Is informing the reader the author's primary goal, or is he rather trying to persuade his audience? (Opinion-forming, propaganda, etc.)
* Is the information based on hard facts or on opinions?
* Is the subject explored from different perspectives?
* Are source references provided?
* What is the quality of the cited sources?
* Is it possible to verify whether the information is correct and complete?
