===007 field===
 +
MARS 2.0 can add an 007 Physical Description Fixed Field when missing. MARS 2.0 takes into account various fields within the Bib record, such as the 300/33X/34X fields, in order to populate the 007 field as accurately as possible. There may be some instances in which an 007 cannot be populated. MARS 2.0 attempts to add a missing 007 for the following: maps, sound recordings, video recordings, and microform.

RDA 2.6: Field Conversions & Additions

Rda2-1.png

A number of MARC update conversions are more complex than simply changing a field tag or subfield code to the current value. Some fields, such as the 007, often need to be added to a record. The special MARC field conversion and additions currently provided are:

  • Add missing format data
    • 007
    • 245 $h (for AACR2 records)*
  • Add missing subfield data
    • 017 $b
    • 032 $b
  • Complex field conversions
    • 1XX Main-Entry-Is-Subject
    • 260 $d to 028 $a
    • 262 to 260
    • 300
    • 301 to 300
    • 305 to 300
    • 300
    • 705 to 700
    • 715 to 710
    • X11

Describe modifications to processing listed above. If any of the MARS 2.0 update special field conversions adds a field identical to a pre-existing field, the identical fields will be deduplicated.

  • PCC recommends retaining GMDs until 2016, with the hopes that ILS will be able to make use of the 33X (Content, Media, Carrier) fields by that time.

Default

Apply all specified field conversions and additions.

Specific Fields

007 field

MARS 2.0 can add an 007 Physical Description Fixed Field when missing. MARS 2.0 takes into account various fields within the Bib record, such as the 300/33X/34X fields, in order to populate the 007 field as accurately as possible. There may be some instances in which an 007 cannot be populated. MARS 2.0 attempts to add a missing 007 for the following: maps, sound recordings, video recordings, and microform.

1xx main-entry-is-subject

In the past, a value of 1 in the 2nd indicator meant the 1XX heading represented both the main entry and a topical subject access point. A MARC update in 1990 made use of the 1XX 2nd indicator for this purpose obsolete.

MARS 2.0 generates a 6XX Subject Added Entry field when the 1XX Main Entry field has 2nd indicator value 1 (main entry is subject). The 2nd indicator of the 1XX Main Entry field is changed to a blank—the only value currently authorized for a 1XX 2nd indicator. The 1st indicator of the new 6XX field will match the 1XX field and the 2nd indicator will be ‘0’.

245 $h added (medium) - AACR2

MARS 2.0 can check for the absence of $h (medium) in the 245 title statement and add a missing general material designation (GMD) in some cases: 

 
   245 10 $a Olympia town square /$c by Fred Smith.
 changes to:
   245 10 $a Olympia town square $h [cartographic material] /$c by Fred Smith.

The following 245 $h GMDs are added based on the values indicated:

245 $h LDR Byte 06 Value 008 Contains
[cartographic material] e or f
[electronic resource] m
[filmstrip] g [33] = f
[kit] o
[microform] a or t [23] = a, b, or c
[motion picture] g [33] = m
[slide] g [33] = s
[sound recording] i or j
[transparency] g [33] = t
[videorecording] g [33] = v

MARS 2.0 can also standardize GMDs already present in 245 $h. MARS 2.0 GMD Standardization is described in Step 3.1. PCC recommends retaining GMDs until 2016.

Note: $h (medium) data in other title fields and subfields are normally deleted in keeping with current cataloging practice (see the Subfield Deletes Table in Step 2.4).

017 field

MARS 2.0 adds $b (Source) if not present in field 017 Copyright Registration Number. The $b in field 017 carries the name of the agency assigning the copyright registration number. Because the $b is now required, and records input before 1980 do not contain it, MARS 2.0 can add the default $b code and data U.S. Copyright Office to field 017.

028 field

If the subfield order in an 028 field is $b $a, MARS 2.0 reorders the subfields so they follow the current standard order of $a $b.

032 field

MARS 2.0 adds $b (Source) if not present in field 032 Postal Registration Number. The $b in the 032 field carries the name of the agency assigning the postal registration number.

Because $b is now required and records input before the subfield was defined do not contain it, MARS 2.0 can add the default $b code and data USPS to field 032.

260 field

MARS 2.0 can convert field 260 $d to field 028 $a. Field 260 $d was defined as “Plate or publisher number,” but was made obsolete when field 028 Publisher Number for Music was defined. If a 260 $d exists in a bibliographic record and the value in Leader byte 06 is c, d, i, or j:

  • 028 field with indicator values 02 is generated
  • 260 $d is moved to 028 $a
  • 260 $b is copied to 028 $b
  • Punctuation in the 260 field is corrected, if necessary

The 260 field conversion option includes special routines that update the punctuation in all 260 fields in the bibliographic records being processed.

These punctuation routines update much of the punctuation in 260 fields to the current standards, including:

  • <space> + <colon> before $b
  • <comma> before $c
  • Final field punctuation, as necessary

Please also see Step 4.3 & Step 4.4 for 260 updates and conversion to 264 fields.

262 field

Field 262 is restricted to pre-AACR2 records for sound recordings. Field 260 is valid for use with all music materials including sound recordings for the data contained in the 262 $a $b $c. Field 028 was defined for the data in the 262 $k $l (lowercase 'L').

If field 262 exists in a bibliographic record:

  • 262 is changed to 260
  • Changes both indicators of new 260 to blank
  • Retains these subfield codes: $a $b $c

For each 262 $k present:

  • 028 field with indicator values 02 is generated
  • 262 $k is moved to 028 $a subfield
  • 262 $b is copied to 028 $b

For each 262 $l (lowercase 'L') present:

  • 028 field with indicator values 12 generated
  • 262 $l is moved to 028 $a
  • 262 $b is copied to 028 $b

If the 262 field does not contain a $k or $l (lowecase 'L'), MARS 2.0 does the following additional conversions:

  • 262 $c is moved to 028 $a with indicator values 02
  • 262 $e is moved to 028 $b with indicator values 12
  • 262 $b is copied to 028 $b
  • 262 $d changed to $c code

After all conversions have been completed, the punctuation in the 028 fields and 260 field is updated.

300 field

Field 300 physical description of the described item includes validation and cleanup for language materials only (Leader byte 06 = a). Non-print bibliographic records (i.e., media, electronic resources, microforms) are not updated during this process. Each option described below can be customized according to your preference.

The following changes are made to the 300 field (further corrections are made in Step 4.5:

  • Various pagination and spacing issues updated
  • Comma is added to page numbers if missing (e.g., 1264 p. becomes 1,264 p.)
  • [various pagings] is changed to (various pagings)
  • Illustrative matter is rearranged to be in correct order
  • Ill., etc is removed if followed by parenthetical illustrative matter (e.g., ill. (ports.) becomes portraits)
  • Numbered plate data in $b is moved to $a; if plate designation is not numbered, it is removed
  • Note: missing ;$c cm. is not added, unless otherwise requested

301 field

In 1983, field 301 was made obsolete for visual materials. Physical description data is now carried in field 300 Physical Description, with the formerly separate color ($c), sound ($b) and videorecording speed ($f) data recorded in field 300 $b.

If field 301 exists in a bibliographic record, MARS 2.0:

  • 301 is changed to 300, with indicator values <blank><blank>
  • Retains $a and $e, with data
  • $d is changed to $c
  • $b $c $f data is combined into single $b

Changes to newly created 300 fields for RDA standards will be made in Step 4.5.

305 field

Field 305 Physical Description for Sound Recordings is a pre-AACR2 field made obsolete by format integration. Field 305 was functionally replaced by field 300 Physical Description.

If field 305 exists in a bibliographic record:

  • 305 is changed to 300, with indicator values <blank><blank>
  • Retains $a and $c, with data
  • $b $d $e $f data is combined into single $b
  • Updates the punctuation

For each $m present in the 305 field:

  • 305 $m is moved to 028 $a with indicator values 02
  • 260 $b is copied to 028 $b 
	260	$a New York, N.Y. $b Columbia,$c 1959.
	305	$a 1 sound disc (20 min.) :$b analog, 33 1/3 rpm, stereo. ;$c 12 in. $m STMA 8007

	  changes to:
	028  02	$a STMA 8007 $b Columbia
	260	$a New York, N.Y. :$b Columbia, $c 1959.
	300	$a 1 sound disc (20 min.) :$b analog, 33 1/3 rpm, stereo. ;$c 12 in.

For each $n present in the 305 field:

  • 305 $n is moved to 028 $a with indicator values 11
  • 260 $b is copied to 028 $b 
	305	$a 1 sound disc (18 min.) $c 10 in. $b 74 rpm $d standard $e monaural $m STMA $n L27410X

	  changes to:
	028  02	$a STMA 3059
	028  11	$a L27410X
	300	$a 1 sound disc (18 min.) :$b 74 rpm, standard, monaural ;$c 10 in.

Changes to newly created 300 fields for RDA standards will be made in Step 4.5.

300 field

The following corrections of common problems are made in the 300 Physical Description field. Further corrections to bring the 300 field up to RDA standards are done in Step 4.5.

  • Various punctuation and spacing issues updated
  • Comma is added to page numbers if missing (e.g., 1264 p. becomes 1,264 p.)
  • [various pagings] is changed to (various pagings)
  • illustrative matter is rearranged to be in correct order
  • ill., etc. is removed if followed by parenthetical illustrative matter (e.g., ill. (ports.) becomes portraits)
  • Numbered plate data in $b is moved to $a; if plate designation is not numbered, it is removed
  • Adds ;$c cm. if missing 
 
       300 $a 1264 p. :$b ill. (ports.).

	  changes to:
       300 $a 1,264 pages :$b portraits ;$c cm.

705 & 715 field conversion

The 705 Added Entry-Personal Name (Performer) and 715 Added Entry-Corporate Name (Performing Group) fields were made obsolete in 1980.

MARS 2.0 converts 705 fields to the equivalent 700 fields and 715 fields to 710 fields, while also adding a relevant relator code $4, as defined by the converted field.

X11 conference name headings

MARS 2.0 updates Conference Name fields 111, 611, 711, 811 to conform to current MARC21 standards. To change the obsolete $b code to $n, MARS 2.0 rearranges the subfields in the proper order and corrects the punctuation. 

	Pre-AACR2
	711  01	$a International Conference on the Chemistry and Uses of Molybdenum, $b 1st, $c University of Reading, $d 1973

	 changes to AACR2 form:
	711  0	$a International Conference on the Chemistry and Uses of Molybdenum $n (1st :$d 1973 :$c University of Reading)
