From your response, I suspect that there really is no way in MarcEdit to
conditionally select a field by position without specific data to work with,
not even using regular expressions with Edit>Find/Replace.
I should have described the context a bit more. SirsiDynix Workflows
requires a unique title control # for loading update records. The batches
of MARC records of concern have no unique ID numbers outside the URLs in the
multiple 856s. The problem lies with updated serial records which include a
cumulating list of 856 fields, one for each serial issue. And the updated
record would always include the first issue in the first 856. This is where
I hoped to get a unique number.
It appears my best course may be to talk to the supplier of the records and
request that they include a unique number in a field with only one
occurrence, ideally the 001 field.
Thanks again,
