A barcode is a visual, machine-readable representation of data; the data usually describes something about the object that carries the barcode. Traditional barcodes systematically represent data by varying the widths and spacing’s of parallel lines, and may be referred to as linear or one-dimensional. Later, two-dimensional (2D) variants were developed, using rectangles, dots, hexagons and other geometric patterns, although they do not use bars as such. Initially, barcodes were only scanned by special optical scanners called readers. Later application software became available for devices that could read images, such as smart phones with cameras. The utility of bar-coding for faster library transactions is time-tested, and more and more computerized libraries in our country are using this technology. The application of barcode technology in circulation system of a library and information technology is most successful due to its speed, accuracy and reliability. Bar-coding though relatively an old technology is one of the important steps in library automation and is still not widely used in libraries. This article covers various aspects of barcode technology and its application in libraries. The barcode was invented by Norman Joseph Woodland and Bernard Silver and patented in the US in 1952. The invention was based on Morse code that was extended to thin and thick bars.
