--- Comment #12 from Katrin Fischer <katrin.fischer at bsz-bw.de> ---
I would love to see clean-up, but not sure how we can best do it.

* Whatever we do, we want to limit to MARC21 installations.
* We don't know if the library has been setting the flag manually in some
cases.
* We will need to access MARC data, which might make any clean-up really slow
on big databases.


Ideas:

Would running misc/batchRebuildBiblioTables.pl.fix the issue now? Then we could
add a database statement recommending to run it.

Could we assume that we only if 942$s exists/is filled, we should set
biblioitems.serial? I think the previously false code, didn't create that
field, right or wrong?


Thinking more about it... what does the alternative sorting do exactly?
It seems to counteract OPACHoldingsDefaultSortField?
