Created attachment 63535 [details] Search result The search result in Staff client treat reference book as item unavailable so if there is a lost/damaged book than it counts both and shows total number of unavailable items. Suppose there is one damage and one reference book than total count of unavailable books is (2) screen shot available, even if there is single reference item it shows unavailable.

Sadly, this is still an issue. I agree, items not for loan should still be counted as available (= on the shelf) or show as 'for reference' like in the OPAC: Items available for loan: Centerville (3). Items available for reference: Centerville [Call number: 005.13/3] (1).
I agree this is a problem. It seems almost redundant when you consider there's a not for loan status that contains descriptions for the OPAC and the Staff interface. Depending on the setup - the display can say Available for reference, unavailable and not for loan all at the same time depending on which interface you look at.
I believe this has been fixed as we now show the specific status and we have the Reference_NFL_Statuses system preference.
