Until the digitization of library catalogs, which began in the 1980s, the primary tool used to locate books was the card catalog, in which every book was described on three cards, filed alphabetically under its title, author, and subject (if non-fiction). Library card catalogs as currently known arose in the 19th century, and Melvil Dewey standardized the index cards used in library card catalogs in the 1870s. 'Kardex' became a common noun, especially in the medical records field where 'filing a kardex' came to mean filling out a patient record on an index card. 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 the 20th century. These edge-notched cards were phased out in the 1980s in favor of computer databases, and they are no longer sold.

In the late 1890s, edge-notched cards were invented, which allowed for easy sorting of data by means of a needle-like tool.

Index cards could be selected and moved around at will to update and compare information at any time.

In the mid 1760s Linnaeus refined this into what we call index cards. His solution was to keep information on particular subjects on separate sheets, which could be complemented and reshuffled. 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. For organizing data, he needed a system for that was expandable and able to be rearranged easily so he kept each datum on an individual sheet, and could add new sheets and reorganize simply.Д¬arl Linnaeus invented the index card in order to help deal with the information overload facing early scientists that occurred from overseas discoveries. Using cards to create an index was the brainchild of 18th-century naturalist Carl Linnaeus, who is known as 'the father of modern taxonomy' for his work on categorizing species. Harrison's manuscript on The Ark of Studies (Arca studiorum) was edited and improved by Vincent Placcius in his well-known handbook on excerpting methods (De arte excerpendi, 1689). The first early modern card index was designed by Thomas Harrison (ca 1640s). Index cards are used for many events and are helpful for planning.

Professional book indexers used index cards in the creation of book indexes until they were replaced by indexing software in the 1980s and 1990s.ДЄn often suggested organization method for bibliographical use is to use the smaller 3-inch by 5-inch cards to record the title and citation information of works cited, while using larger cards for recording quotes or other data. Index cards are used for a wide range of applications and environments: in the home to record and store recipes, shopping lists, contact information and other organizational data in business to record presentation notes, project research and notes, and contact information in schools as flash cards or other visual aids and in academic research to hold data such as bibliographical citations or notes (see Zettelkasten). They are part of standard stationery and office supplies all around the globe. Special divider cards with protruding tabs and a variety of cases and trays to hold the cards are also sold by stationers and office product companies. Cards are available in blank, ruled and grid styles in a variety of colors. The most common size for index card in North America and the UK is 3 by 5 inches (76.2 by 127.0В mm), hence the common name 3-by-5 card.
