Editing Punched card (section)

=== IBM ''Stub card'' and ''Short card'' formats ===
Long cards were available with a scored stub on either end which, when torn off, left an 80 column card. The torn off card is called a ''stub card''.

80-column cards were available scored, on either end, creating both a ''short card'' and a ''stub card'' when torn apart. Short cards can be processed by other IBM machines.<ref name="IBM_1953"/><ref name="IBM_1965_2"/> A common length for stub cards was 51 columns. Stub cards were used in applications requiring tags, labels, or carbon copies.<ref name="IBM_1953"/>
