An information retrieval system is a device interposed between a potential
user of information and the information problem, the purpose of the system is to
computer wanted items and to filter out unwanted items. This goal is pragmatic:
to make acceptable the time required to satisfy the information need, or to
conclude that it cannot be satisfied. In a town's public library, for example,
the card catalogue or online cataloge is an information retrieval system applied
to a local collection of books and other materials. However, as we intend the
term tube understood, information retrieval is a concept that applies to systems
and functions outside as well as within the framework traditional libraries. The
human brain itself can be viewed as an enormously powerful information retrieval
system.
