#700

siku classication number. A three-digit value followed in most cases by a two-digit extension:

Examples

#700 110.77
#700 710.78

The three-digit value is the subject classification (defined here), and the extension is the date (defined here), the purpose being to arrange the materials in chronological order of data of composition. There are sometimes two extensions to differentiate either the period covered by the content or later commentaries:

#700 200.78.88
#700 302.17.88

There are several very large categories of material in the collections where it has been necesssary to adopt a more elaborate means of filing them sensibly:

#700 774.cai|蔡
#700 778.fen|粉粧樓 -- 3
#700 920.bible|classical|1815|newtestament
#700 932.1852

The subject classification is defined by an authority record under field #7SC, and the dynasty under field #7Sc.
