If an item is in Awaiting Lending Request Processing or In Stacks Searching, selecting Mark Found from the request will route it to Awaiting Secondary Label Printing and a CONSIDERING OCLC status. If the request is marked as found from within the Awaiting Lending Request Processing or In Stacks Searching queues, it will route to Item Shipped, and the OCLC status will move to SHIPPED.
