19502014

19502014 is a numeric designation encountered in some archival and data-management contexts. Rather than representing a single year, it is used to encode a time span from 1950 through 2014.

Origin and form: The string is created by concatenating the starting year 1950 and the ending year 2014, typically without a separator. This compact form is convenient for filenames and database keys but can be ambiguous in plain text.

Usage: In library catalogs, digital archives, and research datasets, 19502014 may appear as a label in metadata fields or as part of file names to indicate the period covered by the materials. It is not part of a standardized, formal taxonomy.

Limitations and recommendations: Because it reads as a single number and could be misinterpreted as a specific year or model designation, formal writing usually uses an en dash with a space: 1950–2014, or spelled out “from 1950 to 2014.” For technical contexts, a descriptive filename such as period_1950_2014 is clearer.
