04/04 Chapter 23 Using the MARC Editor 275
To add a subfield to a tag, position your cursor in the tag and click the Insert
subfield button, or select Subfield | Insert Subfield. The Insert Subfield dialog
lists all of that tag's repeatable (R) subfields and all the unused nonrepeatable
(NR) subfields:
Either type the subfield code
in the text box and click Insert
or doubleĆclick on the subfield.
If you're not sure of the
subfield code, use the
scroll bar to look for
the subfield you want.
Note: Depending on your cursor's position, you may receive a message asking
you to confirm the placement of the subfield.
If you inserted a subfield in the wrong place, you can always delete it. Likewise,
if the data in a subfield becomes unnecessary, you can delete the subfield.
However, if there is only one subfield left in a tag, the only way to delete it is by
deleting the tag (unless the tag is required; see page 267).
Don't bother deleting unused subfields. When you save the record, unused
subfields don't take up any extra space, and any subfields that you added but
didn't use are removed. Besides, if a subfield is a default selection for the
template, it always appears when you open the record in the MARC Editor.
To delete a subfield, place the cursor in the subfield and click Delete subfield, or
choose Subfield | Delete Subfield, and then confirm your decision.
Working with subfield data
You modify subfield data just as you would the text in any document. Simply
place your cursor in the subfield and type your changes. The MARC Editor
automatically wraps the text within a subfield.
Note: When you edit data, all of the common textĆediting commands are
available from the Edit menu, including an Undo command for your last
editing action. You can only select the contents of one subfield at a time. If
you try to paste in more text than the tag can hold (see the record size limit
table on page 266), a message appears and the excess is truncated.
