***Holdings Model***

> Within the context of the Holdings schema, we will not attempt to
> distinguish between the types of bibliographic units (basic or
> secondary), nor will we insist on their type of holdings (single-part,
> multipart or serial), other than providing those characteristics at
> the time of report. We will simply consider that a bibliographic item
> may be composed of a certain number of \'parts\', issued over a period
> of time; these parts are modelled as forming a hierarchical tree
> structure. Thus any part may comprise subsidiary parts and each of
> these may contain further subsidiary parts.
>
> For example, a serial may consist of parts corresponding to the basic
> bibliographic unit, the indexes and the supplements. The part for the
> basic bibliographic unit may contain subsidiary parts corresponding to
> annual volumes of the serial. Each volume may contain subsidiary parts
> corresponding to individual monthly issues.
>
> It should be noted that \'part\' is a logical construct that may or
> may not have a 1:1 mapping to the physical \'pieces\' contained in the
> organization\'s collections. For modelling puposes, one piece is
> assumed to correspond to some particular part in a hierarchy of parts.
> This one part a leaf in the tree-structure of parts: it may have both
> superior and subsidiary nodes in the hierarchy. If so, these other
> parts do not themselves correspond to pieces. It is important to note
> that the mapping of parts to pieces at any given site may change over
> time. For example, a serial received in monthly issues will initially
> have the part for each issue correspond to a piece as it is received.
> As issues are bound into annual volumes, the pieces for the issues
> will cease to exist and will be replaced with a piece corresponding to
> the annual volume. The parts for the issues, however, will remain in
> order to describe the logical composition of the serial (and also to
> provide an audit record for the receipt of the individual parts). When
> the part information for the volume is retrieved, it may contain the
> part information for all its subordinate parts, either by including
> the part information itself or by including a summary of the part
> information.

Bibliographic Level View of Holdings

> Bibliographic level view of holdings describes a bibliographic item in
> a generic way, i.e., independently of any specific copy.
>
> Bibliographic-item (Item Identification Area)
>
> Part 1: Bibliographic-part level 1 (General Holdings Area)
>
> Part 1.1: Bibliographic-part level 2 (Extent of Holdings Area)
>
> Part 1.1.1: Bibliographic-part level 3
>
> Part 1.1.2: Bibliographic-part level 3
>
> (\...)
>
> Part 1.1.n: Bibliographic-part level 3
>
> Part 1.2: Bibliographic-part level 2 (Extent of Holdings Area)
>
> (\...)
>
> Part 1.n: Bibliographic-part level 2 (Extent of Holdings Area)
>
> Part 2: Bibliographic-part level 1
>
> (\...)
>
> Part n: Bibliographic-part level 1
>
> This view simply describes a bibliographic item as a series of
> bibliographic parts, which correspond to the ISO definition of a
> bibliographic unit and/or physical unit. Each bibliographic part may
> be made of a number of subsidiary parts, each in turn possibly
> containing a number of further subordinate parts. It is essentially
> the \'publisher\'s view\' of the bibliographic item, i.e. reflecting
> the publisher\'s initial issue or publication of the item. (For
> example, a serial item could have a part called \"v.1:no.1/2\", which
> comprises the two underlying bibliographic parts, i.e. v.1:no.1 and
> v.1:no.2). This model provides for what is usually referred to as
> \'summary holdings\' and \'detailed holdings\'.
>
>  

Copy and Piece Level View of Holdings

> Copy and piece level view of holdings provides the holdings data for
> each individual copy of a bibliographic item and the physical pieces
> comprising the copy. It has the following general structure:
>
> Bibliographic-item (Item Identification Area)
>
> Copy-1
>
> Piece-1.1=Bibliographic-part-1 (General Holdings Area)
>
> Bibliographic-part-1.1 (Extent of Holdings Area)
>
> Bibliographic-part-1.2 (Extent of Holdings Area)
>
> (\...)
>
> Bibliographic-part-1.3 (Extent of Holdings Area)
>
> Piece-1.2=Bibliographic-part-2
>
> (\...)
>
> Piece-1.n=Bibliographic-part-n
>
> Copy-2
>
> (\...)
>
> Copy-n
>
> This view, although similar to the bib level view, describes the
> individual copies of a bib item. Therefore, each copy is also made of
> a number of physical pieces (with characteristics applying to the copy
> only), each corresponding to a single part in the part hierarchy. Each
> part may have parent parts as well as subsidiary parts.

**Holdings Reporting Levels**

> The Holdings reporting levels proposed below are derived from a number
> of standards (ISO 10324, NISO Z39.71 and US-Marc for Holdings), but
> concentrate mainly on the information that is or might be needed from
> the Z39.50 end-user\'s perspective. For the purpose of Holdings, two
> categories of holdings reporting levels are proposed:
>
>  

***Bibliographic Level Holdings***

> Table 1 presents the general content of bibliographic level holdings
> statements at four different levels, defined as follows:
>
> Level B-1: Minimal bibliographic level holdings (i.e. \'Locations
> only\')
>
> Level B-2: Summary Bibliographic Level Holdings (i.e. summary
> information about top-level parts held per location, without details
> of arrangement into physical pieces). This level includes holdings as
> reported to a union catalogue system.
>
> Summary bibliographic level holdings corresponds partly to ISO/NISO
> level-3 holdings statements. This level reports summary holdings at
> the bibliographic level, non copy specific, and makes no distinction
> on how the local institution physically arranges the different
> physical parts. Holdings are provided for all bibliographic units of
> an item, at the highest level of enumeration.
> *SummaryBibLevelHoldings* is a list of *BibParts*, described below.
> None of the BibParts contain subordinate BibParts
>
> Level B-3: Detailed Bibliographic Level Holdings (i.e. detailed
> information about parts held per location, without details of
> arrangement into physical pieces).
>
> Detailed bibliographic level holdings corresponds partly to NISO
> Z39.71 level-4 holdings statement. This level reports the holdings of
> bibliographic units at the lowest level, independently of individual
> copies held by a site. Therefore, a single instance of each bib part
> is provided (i.e. the specific issue held and not the number of copies
> of the issue). *DetailedBibLevelHoldings* is a list of *BibParts*,
> described below. Each BibPart will contain subordinate BibParts, if
> there are any.
>
> Level B-4: Extended bibliographic level holdings (i.e. detailed
> information about parts held per location, including details of
> arrangement into physical pieces with circulation information for each
> piece).
>
> (Please, refer to the corresponding schema definition section for
> detailed definition of each. The \'Holdings Statement\' section
> provides overview of all levels).
>
> In addition, [Appendix A]{.underline} presents the general structure
> of bibliographic level holdings statements.

**Copy Holdings**

> Table 2 presents the general content of copy oriented holdings
> statements at four different levels:
>
> Level C-1: Minimal copy level holdings (i.e. \'Copies only\')
>
> Level C-2: Summary copy level holdings (i.e. summary holdings per
> copy)
>
> Level C-3: Detailed copy level holdings (i.e. detailed holdings per
> copy, down to the piece level)
>
> Level C-4: Extended copy level holdings (i.e. detailed holdings at the
> piece level with circulation information)
>
> [Appendix B]{.underline} presents the general structure of OPAC copy
> level holdings statements.
