## 1.1 : Types of information sources

The publishing industry has adapted to our rapidly changing information society by offering online information sources (books, encyclopaedias, magazines, dictionaries and other materials) either for free or for a fee.

The libraries select information sources based on relevance and quality and make the information available for students and teachers in a structured way. For this information, we distinguish the following categories:

- Catalogues: to search for books, magazines and journals or audiovisual materials
- Databases: to search for articles, summaries, etc.
- Reference works: to search for brief descriptions about concepts, people or words.
