How to search for books by "Status"
Click the down arrow on the "catalog" button and select "cataloging tools"
Select "find and replace" and then change in the drop down from "bibliographic" to "bib-holdings"
Here is a sample search to look up items marked as missing:
Notice the image below where 994#a is circled. This specifies to perform a search in the 994a field of all records instead of "anywhere". The field that is typed in the box next to "anywhere" will always override the search parameters contained in the drop down to the left of it. In the box below, enter the letter "m" (just as circled below) and click on search to retrieve all holdings marked missing.
The image below shows the results for the search. You can retrieve the details for the holding and bibliographic record by clicking on the icon(s) on the right.
