[Koha] displaying item types

Firstly, I really must thank everyone who has responded to my requests for help. I haven't thanked everyone individually but have had really useful answers to the most stupid-sounding enquiries! Another one I'm afraid- where is the switch that enables item types to be displayed in the opac? I get boxes showing location; call number; status and due date. (I don't actually want status or due date so it would be useful to know how to get rid of those too.) Or alternatively is there some other way of displaying the type of item (book, journal or whatever) ? I see on one of the demo sites that the type is displayed underneath the title, not in a box. Either would do me fine, just some way of showing what the item is. Thanks again Jan
