Not all sources are equally good or useful. What counts as a good and appropriate source depends on your subject area and the assignment you are doing. Usually, you should use academic sources, but sometimes other sources, such as expert blogs, can also be appropriate. The important thing is to think carefully about why the information was created, and whether it is reliable and of high quality.
A useful tool is the quick 5 Ws approach.
| WHO | Who wrote it, and can you trust them? Are they an expert in this subject area, or a general writer or journalist? Where might they sit on a continuum between academic/expert <--> individual/journalist? |
|---|---|
| WHERE | Where is it published? Is it in a trusted academic journal or on a general website (eg com or .co.uk)? |
| WHAT | What kind of information is it, and is it useful for your work? Is it research, an opinion or official guidance? |
| WHEN | How recent is it? Is the information up to date? Or is it a key work that may appear dated but is still deemed significant today? |
| WHY | Why was this source created? Is it meant to sell something, persuade people, entertain them, or give information? Is it aimed at university students? Does it show any bias or leave out any important information? |

Hierarchy of Evidence
This helps you look at online information more carefully and decide how reliable it is. Below is one example of a Hierarchy of Evidence, but there are many different versions available online. Although it is mainly used in health-related subjects, it is still a useful way to better understand the quality of research evidence.
