We are using I<magic> which detect repeatable fields only from |
155 |
|
sequence of field/subfield data generated by normalization. |
156 |
|
|
157 |
|
Repeatable field is created if there is second occurence of same subfield or |
158 |
|
if any of indicators are different. This is sane for most cases except for |
159 |
|
non-repeatable fields with repeatable subfields. |
160 |
|
|
161 |
|
You can change behaviour of that using C<marc_repeatable_subfield>. |
