Cecilia has let us know that we need to notify Serials Catalog when we get a report from vendor that a title is "inactive".
In the past, we have left the order open, but extended the claim date for titles that were reported as being "inactive". I would like you to close the order record in these cases using CLS status. Sometimes the vendors keep the order open, sometimes they close, so better to have these closed off. And if the title ever becomes active again and we receive any issues, we can always open up the order again and notify serials cataloging if the record needs to be reopened or notes need to be made on the bib record.
