Step 3.7: Childrens Matching
MARS 2.0 processing can match bibliographic headings against the headings in the Annotated Card Program Subjects Authority File (hereafter referred to as Childrens). Childrens contains just over 960 authority records.
Fields matched
The following fields are matched against the Childrens:
Note: Only those with a 2nd indicator of 1 are Childrens Subjects
Ignore or remove without processing
Some libraries have catalogs that do not contain subject headings coded as Childrens. Other libraries have bibliographic records in their catalog that contain Childrens headings, but their local system is profiled to exclude them from the OPAC indexes.
Most libraries in which the Childrens headings are not used and are not causing any problems for patrons select ignore, where MARS 2.0 ignores the Childrens headings during authority control processing.
Alternatively, you may wish all Childrens subject headings with a 2nd indicator of 1 are removed from the bibliographic records.
Databases and Search Order
If you choose to have your Childrens headings processed, you also have the choice of which database to search against as well as in which order the databases should be searched. The two databases available to search are:
- Childrens Subjects
- LC [Adult] Authority File
Search Childrens authority file only
In this option, MARS 2.0 matches Childrens headings against Childrens only. For those headings that match a heading in Childrens, the indicator remains as 1.
Headings that match a cross-reference in Childrens are flipped to the established form of the heading and the 2nd indicator is again retained as a 1.
After the matching is completed, all remaining Childrens (i.e., those that did not match a heading in Childrens) are retained in the records.
Search Childrens against LC adult only
In the catalogs at some libraries, the presence of Childrens headings in their bibliographic records creates duplicate and sometimes confusing index entries for patrons. These libraries may wish to consider choosing this option:
In this option, MARS 2.0 first matches Childrens headings against LC Adult as if the headings had a 2nd indicator of 0 instead of 1.
For those headings that match a heading in LC Adult, the indicator is changed from 1 to 0.
Headings that match a cross-reference in LC Adult are flipped to the established (adult) form of the heading and the 2nd indicator is again changed from 1 to 0.
After the matching is completed, all remaining Childrens headings (i.e., those that did not match a heading in LC Adult) are removed from the records.
Or, you could choose that any Children’s headings that fail to match LC Adult are retained in the bibliographic record with the original 2nd indicator value of 1.
Search Childrens 1st, LC adult 2nd
Some libraries prefer to search their Childrens headings against Childrens first. Any matches found will update the heading, but the 2nd indicator value will remain as 1.
However, unmatched Childrens headings could then be searched against LC Adult. Any matches found during this procedure would change the value of the 2nd indicator from 1 to 0:
In this option, MARS 2.0 retains unmatched Childrens headings, with a 2nd indicator value of 1, to be searched at a later date by the library (of course, remove unmatched could instead be chosen above if the library preferred that option).
Matched headings for this option could either have a 2nd indicator value of 1 for matches found within Childrens or a 2nd indicator value of 0 for matches found within LC Adult.
This option is particularly useful for libraries interested in updating and retaining their Childrens headings if possible, with the option to upgrade them to LC Adult headings if there is no match during the first pass against the Childrens.
Changing the search order (Adult 1st, Child 2nd) reverses the order in which headings are matched.
Add Juvenile Form Subdivisions to Matched Headings
Adding juvenile form subdivisions to matched headings will update the LC Adult matched headings with $v Juvenile literature (or whatever is specified by the library) to the heading:
childrens heading: 650 1 $a Rain forests. 650 1 $a Collies $v Fiction. matched LC Adult with juvenile form subdivisions applied: 650 0 $a Rain forests $v Juvenile literature. 650 0 $a Collies $v Juvenile fiction.
If your requirements either fall outside of these options or you have questions about Step 3.7, please contact your MARS 2.0 project manager.
If there is an existing $v that contains juvenile anywhere in the subfield, then nothing is added. If there is an existing $v and it does not contain juvenile, the program will lowercase the first letter of the last $v, then insert Juvenile at the beginning of that subfield.
Juvenile rules
If there is no $v in the tag, the program adds $v according to certain criteria within the Leader (LDR) fixed field. If the record is a book (LDR[06] = a or t), then the 008[33] is checked to determine what kind of $v Juvenile ... is added:
- 008[33] = 1 : add $v Juvenile fiction
- 008[33] = d : add $v Juvenile drama
- 008[33] = h : add $v Juvenile humor
- 008[33] = p : add $v Juvenile poetry
Similarly, for software, films, music, and sound recordings each will have its own $v added according to the values in the LDR or 007 fields.
For maps (LDR[06] = e or f), the program adds $v Maps for children on the end of the heading. All other formats will have $v Juvenile literature added to the heading.
