An index card (or record card in British English and system cards in Australian English ) consists of card stock (heavy paper ) cut to a standard size, used for recording and storing small amounts of discrete data. A collection of such cards either serves as, or aids the creation of, an index for expedited lookup of information (such as a library catalog or a back-of-the-book index). This system is said to have been invented by Carl Linnaeus , around 1760.

1053-501: The information overload facing early scientists that occurred from overseas discoveries, though there is room for dispute about whether he alone was the index card's inventor. Linnaeus had to deal with a conflict between needing to bring information into a fixed order for purposes of later retrieval, and needing to integrate new information into that order permanently. His solution was to keep information on particular subjects on separate sheets, which could be complemented and reshuffled. In

1170-627: The mid 1760s Linnaeus refined this into what are now called index cards. Index cards could be selected and moved around at will to update and compare information at any time. In the late 1890s, edge-notched cards were invented, which allowed for easy sorting of data by means of a needle-like tool. These edge-notched cards were phased out in the 1980s in favor of computer databases, and they are no longer sold. James Rand, Sr.'s Rand Ledger Company (founded 1898) with its Visible Ledger system, and his son James Rand, Jr. 's American Kardex dominated sales of index card filing systems worldwide through much of
