Repeatable elements
A manifestation element is either unique or repeatable. A cataloguing agency may record only one occurrence of a unique element. A cataloguing agency may record many occurrences of a repeatable element by recording each value in a separate occurrence of the element.
A unique, non-repeatable element is indicated in ISBDM by the symbol 1 after the element’s label.

ISBDM does not specify a maximum number of occurrences of a repeatable element in the description of a manifestation.
