Block 7XX contains names of persons and corporate bodies having intellectual responsibility for the bibliographic item being described.
Entering personal names in fields 700, 701, 702, 900, 901 and 902 (in further text 70X and 90X), and also corporate names in fields 710, 711, 712, 910, 911 and 912 (in further text 71X and 91X), depends on the existence of authority control for personal names and corporate names within the shared cataloguing system. For the time being the authority control for personal names is implemented in COBISS.SI, COBISS.BG and COBISS.AL, and the authority control for corporate names exists only in COBISS.SI.
By establishing the authority database and introducing the authority control for personal and corporate names into the shared cataloguing system, the data input method in fields 70X, 90X, 71X and 91X has changed. The uniform headings for personal names may be entered in fields 70X only with the authority database, and the uniform corporate headings in fields 71X may be entered from the authority database or can be entered manually. The relationship between authority records and personal names in fields 70X, or corporate names in fields 71X of the bibliographic record is established through subfield 7XX3 – Authority record number (see COBISS3/Cataloguing user manual, chapter Entering data under authority control and see manual COMARC/A Format for Authority Data user manual). The similar holds for entering variant and related headings where the corresponding fields 90X and 91X are generated automatically within bibliographic records.
Within the shared cataloguing system where the authority control for personal or corporate names was not implemented, all relevant subfields within fields 70X and 90X and also fields 71X and 91X should be entered manually.
At fields 70X and 90X there are subfields marked with two asterisks "**" that have been cancelled after the authority control was implemented (though they are still used within the shared cataloguing systems with no authority control present).
