The original database: searchable, sortable, and immune to blue screens.
means A small, stiff rectangle of card stock used to record a single fact, note, or quotation so it can be filed, sorted, and retrieved by hand.
from 'Index' traces to Latin 'indicare' — to point out — via 'index' meaning 'that which points' or 'forefinger,' the finger you'd use to point to an entry in a list. Card cataloguing systems using ruled cards rose in the 1800s as libraries and offices needed a flexible way to track growing collections of information, letting entries be added, removed, or reordered without rewriting an entire ledger. The standard sizes (like 3x5 inches) were later formalized so cards, drawers, and filing cabinets could be mass-produced to fit one another.
