Currency refers to the timeliness of information.
In printed documents, the date of publication is the first indicator of currency. For many other types of data, however, currency is extremely important, as is the regularity with which the data is updated. Where there is a need to add data or update it on a constant basis, the document includes information on the regularity of updates. The document includes a publication date or a last updated date. The document includes a date of copyright.
