Hi to all, working with ACQ, the bibliographic record is creates when I place the order in the basket. In fact I want that patrons don't see the new bibliographic record in the Opac until the copy is arrived and I have finished to catalogue it. I think that I can setup tag 942 in ACQ framework with a specific string like 'ON_ORDER' and I insert the limit 'NOT ON_ORDER' to every search with an Apache enviroment variable. During catalog I will change the 942 to the specif material (Book, Serial, etc.). Do you have test a similiar trick ? If you use ACQ, do you show biblio to users before full cataloging them ?
