|Abstract||The United States Military Academy is faced with the situation whereby 700 cadets may in a single subject prepare computer programs in class one day and get their solutions in the form of a computer runoff at their next class attendance. If the programs had to be processed by conventional keypunch techniques the peak requirements for keypunching would be overwhelming. Keypunched cards with operator errors caused by misinterpreted coding sheets could not be returned to students for review and correction prior to the time the solutions are required in class. This situation has caused the Military Academy to investigate methods bypassing the keypunching operation. A number of special type mark-sense and Port-A-Punch cards have been used. Figure 1 shows a card used with SADSAC, a simplified academic design single address computer; Figure 2, a card for SASSY, a symbolic assembly program; Figure 3, a card for CADETRAN, a dialect of FORTRAN. (It contains the arithmetic statement X = 3.5 * A/(K**2 - C**2).) The CADETRAN/FORTRAN card is printed in four colors. Numbers (which require marking of a single position) are printed in black. Letters of the first third of the alphabet are printed in green, as is the 12-zone position which is identified A→I. Middle third letters of the alphabet are printed in red, as is the 11-zone position identified J→R. The final third of the alphabet is printed in blue as is the 0-zone position, and identified as S→Z. Commonly used symbols which would require 3 marks have been brought out to a separate left column where a single mark serves to identify them. Common but lengthy verbs such as FORMAT, DIMENSION and READ may also be represented by a single mark.|

Ministry of Human Resource Development (MHRD) under its National Mission on Education through Information and Communication Technology (NMEICT) has initiated the National Digital Library of India (NDLI) project to develop a framework of virtual repository of learning resources with a single-window search facility. Filtered and federated searching is employed to facilitate focused searching so that learners can find out the right resource with least effort and in minimum time. NDLI is designed to hold content of any language and provides interface support for leading vernacular languages, (currently Hindi, Bengali and several other languages are available). It is designed to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is being developed to help students to prepare for entrance and competitive examinations, to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is being developed at Indian Institute of Technology Kharagpur.
NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Human Resource Development (MHRD), through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
