18891964

18891964 commonly refers to the span of years from 1889 through 1964. In bibliographic, archival, and metadata contexts, this kind of continuous date range is used as a labeling convention to group materials, events, or data that originate in or relate to this 75-year period. It is not a formal historical term with a single defining framework, but a practical label for organizing information.

The period from 1889 through 1964 encompasses vast social, political, technological, and cultural change. It includes late nineteenth‑century industrial expansion, the two world wars, the interwar years, and the postwar reconstruction era. It also covers the emergence of new technologies such as widespread electrification, mass communication, modern transportation, nuclear developments, and the early space age. Politically, the era saw rapid shifts, including ideological contestations, decolonization processes beginning after World War II, and the growth of international institutions. Culturally, modernist movements, changes in education and media, and evolving social norms developed against a backdrop of global upheaval and reform.

In practice, the 1889–1964 designation is primarily a tool for cataloging and research. It helps researchers locate materials whose most relevant dates span those years, or to study trajectories that extend across late 19th and mid‑20th century contexts. Because it is a broad label rather than a defined epoch, the precise boundaries and characteristics can vary by discipline and source.
