Some libraries request customization of the bibliographic brief record in catalog results. Usually it is a certain MARC tag that is frequently referenced but can't be seen until going into the detail view. One example might be the 082, 035, or an RDA tag. These kinds of requests require adding custom code to control the display. It would be nice if libraries could control that display themselves through a system preference or maybe in the framework. There could be limitations to control the total number of added fields to prevent overwhelming the search results display.
