Changing Non-MARC Fields to MARC

Choose Change non-MARC field to MARC from the Choose Command Type dialog box to open the Change non-MARC Field to MARC dialog box.

Global Update uses the data you enter in the Find text boxes to identify the non-MARC field to change to MARC in the selected records. If you specify a field group tag in the Replace row, it replaces the current field group tag. A MARC tag specification is mandatory; indicators are optional. The system places all data into subfield |a in the specified MARC field.

To change a non-MARC field to MARC:

1. In the Find text boxes, enter the field group tag and data that define the field you want to change. The system changes only the field in the selected records that meets all of the specified criteria.
   
2. In the Replace data text boxes, enter the field group tag, MARC tag, and indicators you want to appear in the MARC field.

3. Choose the Use Displayed Field, Match Case, and Match Whole Field check boxes as desired.
   
4. After specifying the Find criteria and Replace data, choose OK to close the dialog box and return to the Command input tab. The command you created appears as a single line, for example:

The command row includes a Command column and an Action column. The Command column indicates the type of command you specified. (nonMarcTo... = change non-MARC field to MARC.) The Action column indicates the non-MARC field identifying criteria and the MARC data for the copy in the format non-MARC criteria ==> MARC data. MARC tags appear in parentheses and indicators appear in brackets. A wild card character or word, such as a period ('.'), an equal sign ('='), or <any>, may represent some data fields with unspecified (default) content. Selected options check boxes appear as a letter following a slash at the end of the command:

f	Use Displayed Field
w	Match Whole Field
c	Match Case

In the example above, Global Update converts non-MARC data with a 'b' field group tag to a MARC 700 field with no change to the field group tag. For example:

Options Check Boxes

The following check boxes appear in the Change non-MARC Field to MARC dialog box. Select (check) the check boxes to enable the following options.

Use Displayed Field

If you retrieved records using an index search, the specified changes apply to all fields corresponding to the displayed field on the Select Records tab regardless of the MARC tag of the field in which the search term occurs. Other limiting specifications on the command input tab can affect the result. For example, a search of the author index may retrieve records in which an author appears both as a personal name main entry (MARC 100) and as a personal name added entry (MARC 700). If you check the Use Displayed Field check box and enter no other command specifications, Global Update changes both the 100 and 700 fields. Be sure to review the Preview tab list to confirm your results before processing.

If you retrieved records using an Advanced Word Search or a review file, the specified changes apply to the field appearing in the browse list of the Select Records tab. For bibliographic records, Global Update displays the Title field by default. To display a different field in the browse list as the target for change, toggle to the desired field.

Match Whole Field

Information in the Find Data field must match the entire field or Global Update makes no change.

Match Case

The text case of the information in the Find Data field must match the text case found in the corresponding record field or Global Update makes no change.
