Now, it seems that, type icons are prefixed. like in search result page there can be only below types for icons.

The images displayed in the XSLT results screen are, unfortunately, not configurable via Koha's administrative interface. Those "material type" icons are hard-coded. The material type is not defined in the MARC record by the item type but by the material type defined in the leader. The only option at the moment for customizing those icons would be to replace the files on the server with alternatives of your own with the same file names. One of the reasons there is a distinction between material type and item type is that material type is always defined at the bibliographic level. Item type can be defined at the item level. So in some libraries one bibliographic record might have multiple items with different item types. It is for that reason that itemtype and/or collection code are not displayed on the search results screen. -- Owen -- Web Developer Athens County Public Libraries http://www.myacpl.org
