First level of enumeration [matches caption in 853 $a]

 – (if End_Volume for that Holdings record is not blank OR the Acquisition is 4 and this is the highest volume)

End_Volume (if exists and Begin_Volume and End_Volume are not identical)

 

First level of chronology [matches chronology in 853 $i]

Begin_Year (if exists)

/ followed by Cross_Begin_Year (only if exists; do not use / if no Cross_Begin_Year)

- (if End_Year for that Holdings record is not blank OR the Acquisition is 4 and this is the highest year)

End_Year (if exists and End_Year and Begin_Year are not identical – unless there is a corresponding End Volume and End Year must be included to balance holdings)

/ followed by Cross_End_Year (only if exists; do not use /if no Cross_End_Year)

 

See 853/863 Instructions below.

  
853/863 Instructions
:

If General Retention Policy (008 position 12) is 6, do not create an 853/863.  If Encoding Level (Leader position 17) is 2, do not create an 853/863.  Otherwise, the holdings will have to be analyzed to determine if volume and/or year information is present.

 

$8 is a linking field which maps to the appropriate caption (853) and also orders the data from oldest to newest.  It is possible to have more than 10 863s; in that case, the linking numbers could go to two decimals ($8 1.10, $8 1.11, $8 1.12, etc.).

 

Each separate Holdings ID will be placed in a separate 863.  Volumes are placed in $a and years are placed in $i.
