1. Prerequisites and uses of secondary analysis

In the field of documentation and information we normally are provided with references of the sources. The problem of finding relevant material is not only a problem of traditional approaches to literature. It is also one of the main problems in trying to get hold of relevant data. This can be summarised in the empirical research data law:

"The data you have is not the data you want,
the data you want is not the data you need,
the data you need is not available"
