# 4. Evaluate

What have I found and what can I use? After you have searched for and found information, it is important to critically examine whether the information is relevant, reliable, current, and complete.
In general, the sources you encounter in the library are reliable. In addition, many of these sources are the product of organisations (for example, educational publishers) that want to be reliable and try to provide the best possible product by expert editing. Nevertheless, here too, the information can be influenced by the fact that the creators think from a certain academic perspective, a philosophy of life, a commercial point of view, and so on. So always use different sources and compare them with each other.

In this section ‘Evaluating sources’ we will deal with the following:

1. Relevance
2. Reliability
3. Currency
4. Completeness
