- Numbers: Record all numeric designations using Arabic numbers.
v. VIII becomes v.8
no. Five becomes no.5
- Ordinal numbers:
- Alphabetic designations: Record uppercase and lowercase alphabetic data as they appear on the publication (romanized, if necessary).
- Combined numbering: Separate the numbers or alphabetic designations with a forward slash.
- Hierarchical level: Record enumeration data from highest hierarchical level to lowest hierarchical level, using a colon to separate each level.
- Numbered series: Treat series numbering schemes and series captions as the most inclusive level of enumeration data.
- Alternative numbering (parallel numbering): Record alternative numbering following the regular scheme of enumeration and separated using an equals sign. Remember, the numbering on the right side of the equal sign must be continuously incremental.
- Enumeration lacking (serial): If part of an otherwise numbered unit lacks enumeration, supply it in square brackes.
- Enumeration lacking (non-serial): If a multipart non-serial item does not carry enumeration on any part, supply enumeration (along with the appropriate caption). If one or more parts of an otherwise numbered multipart non-serial item lack enumeration, supply the enumeration. Do not use square brackets when supplying the enumeration.
1st volume is titled "Southern States"
2nd volume is titled "Northern States"
- Incorrect enumeration: Record incorrect enumeration as it appears on the publication, with the correct enumeration following in square brackets, preceded by "i.e.". In a compressed statement, the incorrect enumeration is only recorded if it is at the beginning or end of the compressed range.
- Unbroken range: Record an unbroken range of holdings using a hyphen between the first and last numeric/alphabetic designation.
