Subfields

$a Type of date/Publication status.
Subfield $a contains a one-character alphabetic code that indicates the publication status of the reproduction. Codes given are those defined in field 008/06 (Publication Status).
$b Date 1/Beginning date of publication; and, $c Date 2/Ending date of publication.
Subfields $b and $c contain the coverage dates of the reproduction. The dates given generally relate to those given in subfield $m in field 533, when present. If subfield $m is not given and it is unknown with which issue the microform begins or ends, use 19uu, 1uuu, etc., as appropriate. Do not give the dates of filming (533 $d). When supplying dates in subfields $b and $c, follow guidelines given in field 008/7-14.
$d Place of publication, production, or execution.
Subfield $d contains a two- or three- character code that represents the place of publication, production, or execution of the reproduction. The code given relates to the place given in field 533 $b. In coding this subfield, the guidelines given in field 008/15-17 are followed.
$e Frequency; and, $f Regularity.
Subfields $e and $f each contain one-character codes that indiate the frequency and regularity of the reproduction. Codes given in these subfields are those found in field 008/18-19. For microform reproductions that have no specific frequency or regularity, use code "u" in both subfields.
$g Form of item.
Subfield $g contains a one-character code that specifies the form of material for the reproduction in hand (e.g., "a" for microfilm). Codes given are those defined in field 008/23 (Form of Item). When field 539 is input, the same code will be given in both 008/23 and 539 $g.
