The book Practical Applicatons of the Punched Card Method in Colleges and Universities, edited by G. W. Baehne an published by Collumbia University Press in , contains an excellent summary of the state of the art in punched card data processing in , including an appendix that appears to be a reprint of IBM's catalog for that year and. Early punched cards helped to process the United States census in They soon proved useful in calculating invoices and issuing pay slips. As demand for more sophisticated systems and reading machines increased in both the United States and Europe, punched cards served ever-larger data-processing by:

Other articles where Punched card is discussed: Analytical Engine: were to be entered on punched cards, using the card-reading technology of the Jacquard loom. Instructions were also to be entered on cards, another idea taken directly from Joseph-Marie Jacquard. The use of instruction cards would make it a programmable device and far more flexible than any machine then in. Herman Hollerith was an American businessman, inventor, and statistician who developed an electromechanical tabulating machine for punched cards to assist in summarizing information and, later, in accounting. His invention of the punched card tabulating machine, patented in , marks the beginning of the era of semiautomatic data processing systems, and his concept dominated that .

The first commercial data processing machines were punched card tabulating systems. Herman Hollerith () worked at the US Census Bureau during While there he began designing machines that could reduce the labor and time that would be required to process the data that would be collected in the Census. Punched card sorters were a key part of data processing from until the s, used for accounting, inventory, payroll and many other tasks. This article looks inside sorters, showing the fascinating electromechanical and vacuum tube circuits used for data processing in the . A punched card, punch card, IBM card, or Hollerith card is a piece of stiff paper that contained either commands for controlling automated machinery or data for data processing applications. Both commands and data were represented by the presence or absence of holes in predefined positions. Now obsolete as a recording medium, paper tapes constructed from punched cards were widely used.
