index card

Small filing rectangle

An index card is a small, stiff piece of cardstock, typically three by five inches, used for writing notes, storing information, or organizing ideas.

Before computers, index cards were essential tools for researchers, libraries, and recipe collections, with each card holding a discrete piece of information that could be alphabetized or categorized in a file box.

The format remains useful for flashcards, speeches, and brainstorming systems.
