- Abstract
- Provides a history of the development of coordinate indexing and searching. In the 1930s scientists began to use edge notched punched cards for searching. The Batten system was invented in 1944. Following the World War 2 these systems underwent major enhancements: Calvin Mooers built up the punched card system with his Zatocoding, and Mortimer Taube enlarged the peek-a-boo system with his Uniterm development. 2 computerizations' of Taube's Uniterm system led to the present day world of information retrieval
