1. The title comprises more than one physical piece. This can be expressed in either open or closed statements (e.g., _v.; or 3v.; 4 videocassettes or _videocassettes) entered in subfield "a" of the 300 tag or, in the case of reproductions, in subfield "e" of the 533 tag. Create an MFHD based on the captions used on the items. Proper forms and caption abbreviations can be taken from BPPAG policy #6.

2. Supplementary or accompanying material for a single volume title is barcoded and attached to the same MFHD as the primary volume. Accompanying material is expressed in subfield "e" of either the 300 or 533 tag or in a 500 note. Create an MFHD based on the captions used on the items. Proper forms and caption abbreviations can be taken from BPPAG policy #6.

3. PNM: When accompanying material for microforms and non-book items is barcoded for PNM, create an MFHD based on the captions used on the items.

B. Do not create an 86X field on the MFHD when:

1. More than one piece is barcoded but each item record is attached to a different MFHD.

2. If the following situation occurs:

Media Services: Accompanying material for media is not substantial and its presence will be indicated in a 852 subfield z (public display note) attached to the appropriate MFHD.

1. Some of the elements in the MFHD record fixed field are system supplied and cannot be changed. Other elements are unprotected and can be modified. Always use lower case letters for the fixed field notes. Underlined elements must be filled in.

1.1				Format h (system supplied)
1.2				Date entered: (system supplied)
1.3				Date revised: (system supplied)
1.4		Leader		Record status: "n" (new) and status "c" (corrected or revised) "d" supposedly will logically delete the record, but the MFHD label will remain attached to the bib record and the MFHD information will still be displayed in the staff mode and to the public unless suppressed
1.5		Leader		Type of Record: "y" for serial item holdings, "v" for multipart item holdings [set], or "x" for single part item holdings [1 v.].
1.6		Leader		Encoding level: Indicates the level of the holdings data in the variable fields. UK's level is "4" and the field is required. This also relates to the first indicator of the variable fields.
1.7		008		Receipt status: 0=Unknown 1=Other receipt or acquisitions status 2=Completed (one item or all items have been received) 3=On order (nothing received yet) 4=Currently received 5=Not currently received |=no attempt
1.8		008		Method of acquisition: d=Deposit e=Exchange f=Free g=Gift p=Purchase u=Unknown z=Other method |=no attempt
1.9		008		Intent to cancel: NOT IN USE YET.
1.10		008		General retention: This code can be a local decision. 0=Unknown 1=Other general retention policy 2=Retained except as replaced by updates 3=Sample issue retained 4=Retained until replaced by microfilm 5=Retained until replaced by cumulation 6=Retained for a limited period 7=Not retained 8=Permanently retained |=no attempt The most frequent code for this field will be "8"
1.11		008		Specific retention: NOT YET IN USE
1.12		008		Completeness code: "0" (Used when holdings are given in 8xx fields).
1.13		008		Lending policy: "u" (This can be changed by the circulation point).
1.14		008		Reproduction policy: "u" (This can be changed by the circulation point).
1.15		008		Language: refers to the language of the captions in the MFHD, not the language of the item. Use the three character code from the bibliographic language tables.

For 866, 867, and 868 tags: Abbreviate captions according to AACR2 and the Caption Dictionary in Policy #6.

If no specific caption is present, use the name of the unit as a supplied designation instead. Capitalize the first word of the name of the unit and enclose it in quotation marks. (It is not necessary for the name of the unit to be an exact transcription of the data from the item).

Examples:

866:41:	|a	"Statistical updates" (Name of unit used).
866:41:	|a	"Atlas" (Designation supplied: item reads "A demographic atlas of Australia".

For an option:

Specific Extent notes contain information clarifying or enlarging upon the extent of the holdings element or elements preceding it. They are recorded in brackets and can include router notes pertinent to a particular piece. Which subfields to use is determined by whether the note is public or private.

Examples:

866:41:	|a	v.1	|z <non-circulating>
866:41:	|a	v.4,	|x <v.5 claimed>
866:41:	|a	v.6
