:Report the institution identifier for each bibliographic item, regardless of retention policy or completeness of holdings. Minimally, it consists of an item identifier for the bibliographic item for which holdings are recorded and a location identifier. The item identifier may be contained in field 004 Related bibliographic record identifier. The location identifier is contained in subfield $a Institution identifier of field 252 Location and call number.

==3.2 Levels of Holdings Statements==
According to the guidelines for applying ''[https://www.iso.org/standard/18372.html ISO 10324 : 1997 ''Information and documentation –Holdings statements – summary level]'', the holdings statement can have 3 levels:
'''Level 1 holdings'''
:Level 1 identifies the item and the holding institution. This level is sufficient for single -part items, but gives no indication of extent of holdings for multipart items and continuing resources items.
:Report the institution identifier for each bibliographic item, regardless of retention policy or completeness of holdings. Minimally, it consists of an item identifier for the bibliographic item for which holdings are recorded and a location identifier. The item identifier may be contained in field [[hold/004|004 Related bibliographic record identifier]]. The location identifier is contained in subfield [[hold/252#a|$a Institution identifier]] of field [[hold/252|252 Location and call number]]. '''Levels 2 and 3 holdings'''
:Level 2 adds to le vel 1 general guidance as to the extent of an institution's holdings. Minimally, in addition to the requirements for level 1, it could include:
::Receipt or acquisition status ([[hold/170 |170]] $a/0)::General retention policy ([[hold/171|171 ]] $a/0)::Completeness designator ([[hold/171|171 ]] $a/5)
Level 3 includes a statement of summary extent of holdings.
:1. Determine the basic bibliographic unit(s) and the secondary bibliographic unit(s) for the bibliographic item.
:2. Determine whether each unit is continuing resources, multipart or single -part.
:3. Report general holdings (level 2) or extent of holdings (level 3) for each unit as indicated under the description of the data elements.
level of enumeration and chronology, in one or more of the following holdings data fields:
*[[hold/500|500 Caption and patterns – basic bibliographic unit]]*[[hold/501|501 Caption and patterns – secondary bibliographic unit supplementary materials]]*[[hold/502|502 Caption and patterns – secondary bibliographic unit indexes]]

The following are examples of bibliographic items and their corresponding units in the ISO standard:
==3.3 Control Functions==
Control functions permitted in the ''UNIMARC Holdings Format '' are confined to those used forsubfield codes, field separators, and record terminator, as specified in [[wikipedia:uk:ISO 2709|ISO 2709]]; character set escapesequences as specified in [[wikipedia:en:ISO/IEC 2022|ISO 2022]]; and those for indicating filing information, superscripts, andsubscripts as specified in [https://www.iso.org/standard/13047.html ISO 6630]. No control functions are allowed to specify typographicalfunctions such as italics. The use of control functions in ''UNIMARC Holdings Format '' records is fullydescribed in the ''[[UNIMARC для бібліографічних записів|UNIMARC Manual Bibliographic Format]]'', [[Додаток J|Appendix J]].
==3.4 Field and Subfield Repetition==
A complete record, fully content designated, is naturally the preferred record for international
exchange purposes. In some cases, however, it may not be possible to convert a national record into
the ''UNIMARC Holdings Format '' and provide the full content designation and coded information as
prescribed. To minimize the ambiguities that could result if the indication of this lack of information
were left to the discretion of each national agency faced with the circumstances described above, a
character, hereafter referred to where this occurs as a "fill character," is used in place of the required
information. This character will be the "'''|'''" (vertical line, code table position 7/12 in [[wikipedia:en:ISO/IEC 646|ISO 646]]).
The fill character can be used whenever a content designator or coded information cannot be
determined by the encoding agency. It thus occurs in the following situations: : i) encoding agencydoes not use this content designator or code this information, or :ii) encoding agency uses this contentdesignator or codes this information but in this particular record does not know the correct value, or:iii) encoding agency uses similar values for this content designator or coded information but theycannot be translated to the exact ''UNIMARC Holdings Format '' equivalents.
The following rules apply to the use of the fill character: fill characters may only be used for
indicators and coded data values that are not mandatory, thus fill characters may not be used in the
[[Hold/Record label|Record Label ]] or [[Hold/Directory|Directory ]] as subfield identifiers or to replace punctuation or other special charactersin the data portion of fields.
==3.7 Coded Data Values==
The following conventions are used in the assignment of coded values in the [[ Hold/Record label|Record Label ]] and coded
data subfields:
:'''<nowiki># </nowiki>''' - '''Information not available'''.:'''u ''' - '''Unknown'''. Used when codes are being assigned, but the appropriate specific value cannot be determined.:'''x ''' - '''Not applicableapplica'ble'''. Used when a characteristic is not appropriate for the type of entity being described.:'''y ''' - '''Not present'''. Used when the characteristic being coded is not present for the entity being described.:'''z ''' - '''Other'''. Used when codes are being assigned and the characteristics of the entity are known, but none of the defined codes is appropriate.:'''| ''' - '''Fill character'''. Used when no attempt is being made to assign the codes.

This format is designed to support primarily the communication of holdings entry records. These
records may also carry alternative entry holdings related to the location and access, for which the
record was created. A [[hold/5xx5XX|5--]] field is used for specifying the pattern, caption, enumeration and
chronology of a holding.
