19211995

19211995 is a concatenated form of the years 1921 and 1995. In index and archival practice, the string is sometimes used as a compact label for a time span that runs from 1921 through 1995, inclusive, to designate the period covered by a subject, collection, or set of materials.

The period encompasses major 20th-century developments: the aftermath of World War I and the interwar years; the Great Depression beginning in 1929; World War II from 1939 to 1945; the postwar order including reconstruction and the emergence of the United Nations; the Cold War era; decolonization and global political shifts; and the rise of information and communications technologies through the 1990s. The span thus includes both dramatic conflicts and long-term social, economic, and technological transformations.

In libraries, museums, and media catalogs, 19211995 may be used as a metadata field to indicate the time span for an artist’s career, a collection, or a body of work that spans those years. It is not a formal title and does not imply any single event or entity; rather, it functions as a temporal boundary to aid organization and retrieval.

The label is ambiguous without context; when encountered, it is helpful to consider the subject matter, geographic scope, and the nature of the materials to interpret the relevance of the time range.
