Repeating Numbers

Per RDA 2.6.2.3 (formerly AACR2 12.3C4), "if the designation consists of a year and a number that is a division of the year, give the year before the number."

CONSER example (8.5.5):

On piece:

no. 1 1990 (no. 1 repeats each year)

In record:

362 0# $a 1990, no. 1-

MFHD:

Volume 1990 incomplete; volume 1991 complete:

Volumes 1990 and 1991 complete (compressed):

Item record:

If volume uses chronological enumeration (i.e. year) and cannot be bound as one physical volume, part designation is based on bibliographic parts. To simplify workflow, record years functioning as enumeration in Voyager CHRON field. If the year enumeration is further subdivided by numerical part numbers, and the year must be bound in multiple physical volumes, record the numerical part numbers after the year in the Voyager CHRON field. Use a colon to separate the (volume) year from the part numbers.

EXAMPLE

MFHD:

Volume 1990 incomplete; volume 1991 complete:

Item record:

CHRON 1990:no.1-5

CHRON 1990:no.7-12

CHRON 1991:no.1-6

CHRON 1991:no.7-12

Rationale:

• enumeration in item records displays when the item is charged
• physical part numbers are misleading for users and ILL when displayed
• misleading for staff view when holdings are compressed
• citation is likely to include part number

using bibliographic part numbers will get item records in synch with MFHD and will clarify holdings when compression is used in MFHD.

Obsolete Former Practice​

If volume uses chronological enumeration (i.e. year) and cannot be bound as one physical volume, part designation is based on physical parts, i.e.:

CHRON 1990:1

CHRON 1990:2
