Step 2.7 Question
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 subfield
- Add missing subfield data
- 017 $b subfield
- 032 $b subfield
- Complex field conversions
- 1XX Main-Entry-Is-Subject
- 260 $d subfield to 028 $a subfield
- 262 to 260
- 300
- 301 to 300
- 305 to 300
- 705 to 700
- 715 to 710
- X11
Indicate whether you want MARS 2.0 to perform special MARC21 field conversions and additions in Step 2-7. Describe modifications to processing listed above. Provide a different default for the 007 field by listing specific values for each position.
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.
Specific Fields
007 Field
MARC update processing can add an 007 Physical Description Fixed Field containing default values. This table shows the format of the record, the values the format is based on and the values in each default 007 field:
| Record Format | LDR Byte Values | Default 007 |
|---|---|---|
| Map | 06 = e or f | ajlcanzn |
| Sound Recording | 06 = I or j | sdlbungnnmmneu |
| Videorecording | 06 = g and 008, 33 = v | vflcbahou |
1XX Main-Entry-Is-Subject
In the past, the second indicator for 1XX Main Entry fields indicated when the 1XX field served a dual function within the bibliographic record. A value of 1 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 second indicator for this purpose obsolete.
Standard MARS 2.0 update processing generates a 6XX Subject Added Entry field when the 1XX Main Entry field has second indicator value 1 (main entry is subject). The second indicator of the 1XX Main Entry field is changed to a blank—the only value currently authorized for a 1xx second indicator. The first indicator of the new 6XX field will match the 1XX field and the second indicator will be ‘0’.
245 $h Subfield Added (Medium)
MARS 2.0 processing can check for the absence of a $h subfield (Medium) in the 245 Title Statement and add a missing General Material Designation (GMD) in some cases:
Example: 245 10$aOlympia town square /$cby Fred Smith. changes to: 245 10$aOlympia town square$h[cartographic material] /$cby Fred Smith.
The following 245 $h subfields 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 | byte 33 = f |
| [kit] | o | |
| [microform] | a or t | byte 23 = a, b or c |
| [motion picture] | g | byte 33 = m |
| [slide] | g | byte 33 = s |
| [sound recording] | i or j | |
| [transparency] | g | byte 33 = t |
| [vidoerecording] | g | byte 33 = v |
To modify any values in this tables, please indicate any changes in Step 2-7.
MARS 2.0 update processing can also standardize GMDs already present in the 245 $h subfield. MARS 2.0 GMD Standardization is described in Step 2-9.
Note: $h Subfields (Medium) in other title fields and subfields are normally deleted in keeping with current cataloging practice (see the Subfield Deletes table in Step 2-5).
017 Field
MARS 2.0 update processing adds $b subfield (Source) if not present in field 017 Copyright Registration Number. The $b subfield in field 017 carries the name of the agency assigning the copyright registration number. Because the $b subfield is now required, and records input before 1980 do not contain it, MARS 2.0 update processing can add the appropriate $b subfield 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 update processing adds $b subfield (Source) if not present in field 032 Postal Registration Number. $b Subfield in the 032 field carries the name of the agency assigning the postal registration number. Because $b subfield is now required and records input before the subfield was defined do not contain it, MARS 2.0 update processing can add the appropriate $b subfield code and data “USPS” to field 032.
260 Field
MARS 2.0 update processing can convert field 260 $d subfield to field 028 $a. Field 260 $d subfield was defined as “Plate or publisher number,” but was made obsolete when field 028 Publisher Number for Music was defined. If a 260 $d subfield 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 subfield & contents moved to 028 $a subfield
- 260 $b subfield contents copied to 028 $b subfield
- 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 subfield
- <comma> before $c subfield
- Adding the appropriate final field punctuation
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 subfields. Field 028 was defined for the data in the 262 $k $l subfields.
If field 262 exists in a bibliographic record, MARS 2.0 update processing:
- Changes the tag from 262 to 260
- Ensures first & second indicators are blank (in accordance with current MARC21 Bibliographic Format)
- Retains the subfield codes: $a $b $c
For each 262 $k subfield present, MARS 2.0 update processing:
- 028 field, with indicator values ‘02’ is generated
- 262 $k subfield & contents moved to 028 $a subfield
- 262 $b subfield contents copied to 028 $b subfield
For each 262 $l (lowercase L) subfield present, MARS 2.0 update processing:
- 028 field, with indicator values ‘12’ generated
- 262 $l subfield & contents moved to 028 $a subfield
- 262 $b subfield contents copied to 028 $b subfield
If the 262 field does not contain a $k subfield or $l subfield, MARS 2.0 update processing does the following additional conversions:
- 262 $c subfield & contents moved to 028 $a subfield with indicator values ‘02’
- 262 $e subfield & contents moved to 028 $b subfield with indicator values ‘12’
- 262 $b subfield contents copied to 028 $b subfield
- 262 $d subfield code changed to $c subfield code
After all conversions have been completed, the punctuation in the 028 fields and 260 field are updated.
300 Field
The cleanup of the 300 field takes place only on records marked with ‘a’ in leader byte 6. Non-print bibs such as media, electronic resources, microforms, etc. are left as-is. Here’s a list of changes that are made:
- 300 $a = 'unp.' [or] 'n.p.' is changed to '1 v. (unpaged)'
- 300 $a = a comma is added to #### page numbers if missing (ex.: 5332 p. becomes 5,332 p.)
- 300 $a = 'l.' is changed to 'leaves'
- 300 $a = 'approx.' is changed to 'ca.'
- 300 $a = preliminary leaves and it’s abbreviation (p.l.) are removed (ex.: 4 p.l., xv, 312 p. = xv, 312 p.)
- 300 $a = 'unnumbered' is removed and brackets added (ex.: 48 unnumbered leaves = [48] leaves)
- If the p. is up against the :$b or the illustrative matter is up against the ;$c we add a space to separate
- 300 $a = Missing periods are added to 'p' (ex.: 135p = 135 p. )
- 300 $b = The illustrative matter is rearranged to be in correct order
- 300 $b = Obsolete illustrative matter is replaced with 'ill.' (ex.: 'tables' or 'fronts.' = 'ill.')
- 300 $b = If 'ill.' is followed by the parenthetical illustrative matter, 'ill.' is dropped and the parenthetical matter remains (example: $bill. (ports.) = $bports.)
- 300 $b = illus. is changed to ill.
- Adds missing semicolon before $c
- Adds ;$ccm. if missing from 300 field
- [various pagings] = changes brackets to parentheses
- If there is no 300 and the record is a book, the default of $ap. ;$ccm. is added
- If there is numbered plate info in the $b that is moved to the $a – if plate designation is not numbered, it’s deleted
Examples 300 $a22 l. :$bgraphs. 300 $aunp. $billus. $c30 cm. changes to: 300 $a22 leaves :$bill. ;$ccm. 300 $a1 v. (unpaged) :$bill. ;$c30 cm.
301 Field
In 1983, field 301 was made obsolete for visual materials. Physical description data is now carried in field 300 Physical Description, with the formerly separate color ($c), sound ($b) and videorecording speed ($f) data recorded in field 300 $b subfield.
If field 301 exists in a bibliographic record, MARS 2.0 update processing:
- 301 tag changed to 300 tag
- Ensures first & second indicators are blank
- Retains subfield codes $a and $e and data
- $d subfield code changed to $c subfield code
Data from field 301 $b $c $f subfields is combined into a single $b subfield in field 300.
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, MARS 2.0 update processing:
- 305 tag changed to 300 tag
- Ensures first & second indicators are blank
- Retains subfield codes $a and $c
- Concatenates the contents of $b $d $e and $f subfields present into a single $b subfield
- Updates the punctuation
For each $m subfield present in the 305 field, MARS 2.0 update processing:
- 028 field, with indicator values ‘02’ and $a subfield generated
- 305 $m subfield contents moved to 028 $a subfield
- 260 $b subfield & contents copied to 028 $b subfield
For each $n subfield present in the 305 field, MARS 2.0 update processing:
- 028 field, with indicator values ‘11’ (one one) and $a subfield generated
- 305 $n subfield contents moved to 028 $a subfield
- 260 $b subfield & contents copied to 028 $b subfield
Example #1 260 $aNew York, N.Y. $bColumbia,$c1959. 305 $a1 sound disc (20 min.) :$banalog, 33 1/3 rpm, stereo.;$c12 in. $mSTMA 8007 changes to: 028 02 $aSTMA 8007$bColumbia 260 $aNew York, N.Y. :$bColumbia,$c1959. 300 $a1 sound disc (20 min.) :$banalog, 33 1/3 rpm, stereo. ;$c12 in.

705 & 715 Field Conversion
MARS 2.0 update processing converts 705 tags to the equivalent 700 tag and 715 tags to 710. MARS 2.0 update also adds a Relator Code ($4) subfield. The default content of the added subfield $4 is prf, the code for “performer.”
Note: Indicate in Step 2.7 if you would like a value different from prf in the new subfield $4.
MARC History
The 705 Added Entry-Personal Name (Performer) and 715 Added Entry-Corporate Name (Performing Group) fields were made obsolete in 1980.
X11 Conference Name Headings
MARS 2.0 updates Conference Name fields [111, 611, 711, 811] to conform to AACR2 and current MARC21 standards. To change the obsolete $b subfield code to $n, MARS 2.0 update processing rearranges the subfields in AACR2 order and corrects the punctuation.
Example #1 Pre-AACR2 711 01 $aIndiana University Eighteenth Century Conference, $b6th, $d1970 changes to AACR2 form: 711 0 $a Indiana University Eighteenth Century Conference$n(6th :$d1970) Example #2 Pre-AACR2 111 01 $aInternational Conference on the Chemistry and Uses of Molybdenum,$b1st, $cUniversity of Reading, $d1973 changes to AACR2 form: 111 0 $aInternational Conference on the Chemistry and Uses of Molybdenum$n(1st :$d1973 :$cUniversity of Reading)
