Abstract

Introductory paper in an issue devoted to theory and foundation of information retrieval. There are too many records to be handled rationally and comfortably. Too much is badly written or repeats what has been adequately stated before. Automated retrieval systems may help society to cope with some information problems, but truly effective systems could help much more. This issue deals (through an examination of the theory and foundations of information retrieval) with how effective information retrieval systems could be designed and discusses important issues of data retrieval
