FIELD DEFINITION AND SCOPE

Time period code (subfield $a) and/or a formatted time period (subfield $b or $c) associated with a 15X heading in an established heading record or a 18X heading in a subdivision record.
Time period code in subfield $a is derived from the B.C. (Before Common Era) and/or C.E. (Common Era) lists in the Time Period Code Table provided under the description of subfield $a.

GUIDELINES FOR APPLYING CONTENT DESIGNATORS

INDICATORS
First Indicator - Type of time period in subfield $b or $c
Whether a subfield $b or $c is present in the field; and, when subfield $b or $c is present, the type of time period it contains. The values distinguish among a single date/time, multiple single dates/times, and a range of dates/times.
'#' - Subfield $b or $c not present
0 - Single date/time
Subfield $b and/or $c is present and contains a single date/time.
150 ##$aLunar petrology
045 0#$c2500000000
1 - Multiple single dates/times
Multiple $b and/or $c subfields are present, each containing a date/time. A range of dates/times is identified by value 2.
045 1#$bd1972$bd1975
[1972 and 1975]
2 - Range of dates/times
Two $b and/or $c subfields are present and together express a range of dates and/or times. Multiple single dates and/or times are identified by value 1.

For B.C. dates, the lowercase alphabetic character represents the millennium and the digit represents the century. If the century is not known, a hyphen (-) is used instead of a number. A single century or a period within a century is coded by repeating the appropriate two-character code to create the required four-characters.
