When no items in a record can be put on hold (for example, if the library does not allow on-shelf holds, and all items are available), the 'Place hold' button still appears in the search results in the OPAC. This can be confusing to patrons. To reproduce: 1. Circulation rules must prevent on-shelf holds (I used just one all/all rule with If all unavailable to prevent crossing the streams) 2. In the OPAC, make a search that will give you a couple of results 3. Find a record where all items are available --> Place hold button is visible 4. Log in (so that Koha knows your patron category and library) 5. Redo steps 2 and 3 --> Place hold button is visible 6. Click 'Place hold' --> No items can be put on hold
