3 Tidsperioder – tilläggskoder
Use TIME PERIOD 3* Qualifier codes WITH appropriate subject codes for: indicating the time period range of a works content, such as the period covered by an art book (A*), a history book (N*), a memoir or biography (DN*), historical fiction (FV*), a children’s history book (YNH*), etc. National extensions (i.e. 3*-xx- format codes, where ‘xx’ indicates a country code) are for specific named periods of time that are important in particular markets but do not necessarily fit neatly into the structure of the general TIME PERIOD qualifiers. All national extensions are sub-categories of a core time period code, so can be mapped back to a standard period. National extensions can be assigned by any user, and are not exclusive to users in the indicated country. TIME PERIOD qualifiers are usually used in conjunction with PLACE 1* qualifiers. (Specific historical events or individual years would be conveyed in detail elsewhere in a products metadata, for example by the title, the table of contents, the descriptive text or keywords). DO NOT USE: for indicating the year of an annual or road atlas or travel guide or the year a work was originally published in, (this is described in other metadata). DO NOT USE: code “3” itself, but select appropriate specific qualifiers from section 3*. Se även:
