Hi Luis, I am not sure I understand your question. By default Koha will display and allow search for items with and without items. You can hide a record when all items on it are hidden with OpacHiddenItems or hide a record by adding 942$n = 1 and turning on OpacSuppression. Hope this helps, Katrin On 12.06.2017 16:51, Luis Moises Rojas wrote:

Hi everybody,

We have PDF books, these books HAVE NOT ITEM associated, How can we SAY: BOOKS with no ITEMS could not be display, but PDF YES?

Thanks
