In library catalogues and databases, you often come across keywords. Keywords characterise the content of a document and are assigned by professionals. The advantages of searching with keywords are:
- You find all publications on that subject; you don’t have to search with all word variants or synonyms
- You know that a publication is really about that subject If you search the NHL Stenden catalogue for problem neighbourhoods, you will find fewer publications than with the keyword disadvantaged neighbourhoods.
