Hi Peter, You can accomplish this in a couple different ways. There's the OPACHiddenItems <https://koha-community.org/manual/18.05/html/02_administration.html#opachiddenitems> setting which lets you define specific item fields that mean an item should be hidden in the public catalog. So you could say that items with a certain "lost" value don't appear. Then there's also a field on the MARC record itself, 942 $n, which you can set to "yes" to suppress an item. This MARC field is tied to the OpacSuppression <https://koha-community.org/manual/18.05/html/02_administration.html#opacsuppression-opacsuppressionbyiprange-opacsuppressionredirect-and-opacsuppressionmessage> settings which give you further control over how suppression works (e.g. you could have it only pertain to certain IP addresses).
Note that these two methods happen at different levels of granularity—OPACHiddenItems would let you, for instance, hide one item (say an insert on a record for a DVD) on a record that otherwise still shows up in the OPAC, while hiding the MARC record will also, of course, hide *all* items attached to it regardless of their field values. Hope that's helpful.
