MARC Label Names

The MARC Label Name file contains alternate field names for display in WebPAC. These names display instead of the variable-length field names for certain tagged fields, if they are in MARC format and meet other criteria established by the MARC Label Name file. In WebPAC, the fields are specified in the Record Display Definition (webpub.def) file, which can be edited by library staff.

The standard webpub.def file contains entries for the following fields:

Record Type	Tags
Bibliographic Records	a, b, d, e, g, h, i, n, p, r, s, t, u, w, x, y, z
Item Records	&

When the system displays a record in WebPAC, it checks the tags of all displayable fields. For each field whose tag matches any of those in the webpub.def file, if that field is in MARC format, the system checks if the field's MARC tag and indicators match those in the corresponding entry in the MARC Label Names file. If the MARC tag and indicators match, the MARC Label Names file entry is used rather than the variable-length file entry.

The MARC Label Name file may also be used to suppress MARC fields from display in the public search function by leaving the field's label blank.

Data Elements

Each entry in the MARC Label Name file consists of the following elements:

Element Name	Description
RECORD TYPE	Specifies the record type.
FIELD TAG	Specifies the tag of the MARC field. If you are not sure to which field tag your library maps a specific MARC tag, view your load tables. For most libraries, the load table used for importing fully catalogued bibliographic records is m2btab.b.
MARC	Specifies the MARC tag(s) and optional indicators of fields to which the label should apply. Standard regular expression special characters are supported. See Regular Expression Syntax below.
LABEL	Specifies the field label to display. Can be a maximum of 39 characters. Leaving this element blank suppresses the MARC field from displaying in WebPAC. If the FLD_LABEL_VERBATIM Web Option is set to a "TRUE" value, the label displays exactly as it appears in this element. Otherwise, the first letter of the label is capitalized and the remaining characters appear in lowercase.

Editing the MARC Label Name File

1. In the Select file drop-down menu in the ASAA function, choose MARC Label Name and then Select.
2. Double-click the MARC label you want to edit.
3. The MARC Label Name file is an internationalized file. If your library has been set up for more than one language, the Edit window includes separate text boxes for input of labels for each of these languages.
4. Enter the label parameters in the Edit window, and select OK.
5. Select the Save tool to save your changes.

Regular Expression Syntax

• To specify all indicators, omit specific entries for indicators. For example:
  
  
  MARC:  655
  LABEL: Genre
  
  In this example, a 655 MARC field with any combination of indicators will display as Genre.
• The caret (^) indicates anything other than the value that follows. For example:
  
  
  MARC:  555[^0]
  LABEL: Indexes
  
  In this example, a 555 MARC field with any first indicator other than 0 and any value in the second indicator display as Indexes. Brackets must enclose this condition.
• The period (.) indicates all values including 'blank'. For example:
  
  
  MARC:  780.4
  LABEL: Formed by
  
  In this example, a 780 MARC field with any first indicator and a second indicator of 4, display as Formed by.
• Multiple values and ranges are enclosed in brackets. For example:
  
  
  MARC:  2461[01]
  LABEL: <No Label Specified>
  
  In this example, a 246 MARC field with a first indicator of 1 and second indicator of 0 or 1 do not display because no label has been specified and thus the field is suppressed from display.
  
  
  MARC:  59[0-7]
  LABEL: Local Notes
  
  In this example, a MARC field with tags 590 to 597 and any value in the first and second indicators display as Local Notes.
