Field 539 is used in OCLC records for reproductions in conjunction with field 533.  Field 539 contains codes that describe the attributes of the reproduction while the 008 Fixed-Length Data Elements field in these records describes the attributes of the original.

Field 539 is input as a character string (similar to field 007) following field 533.  Codes used in field 539 are those used in the corresponding 008 Fixed-Length Data Elements field.

533 ## Microfilm. $m 1902-1937:[Gaps] $b Cambridge, Mass. : $c Harvard University Library Reprographic Service, $d 1991. $e 7 microfilm reels ; 35 mm.

For further examples, see field 533 $m.


$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.

$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.

$f   Regularity.

Subfields $e and $f each contain one-character codes that indicate 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.


Field 539 is used for data entry in lieu of the MARC 21-defined subfield $7 in field 533.

The field was defined by OCLC for ease of input.  Field 539 is output as field 533 $7.
