Notes on Field Contents
The highest level of enumeration and chronology data should be recorded for multipart and serial
units, e.g., earliest and latest date or lowest and highest volume held, or both, with the range of
holdings being broken only by the recording of gaps.
Data is recorded and displayed in a positive sense; that is, emphasizing that which is held rather than
that which is not.
When both are present, enumeration and chronology data should be recorded and displayed together,
enumeration first, with the corresponding chronology enclosed in parentheses. If the preferred form of
display is not possible, enumeration and chronology may be displayed separately, with or without
parentheses.
