The list of material types used across our consortium is very long. Even though we have turned off those that we don't use, we still have a list of about 65. For most of our libraries, this is overkill, as locations like our Chemistry library only use 4 or 5 at most. Catalogers have to use the full list, which increases the chance of confusion or clicking on the wrong thing for even straightforward cataloging. I want to be able to restrict the material types that can be used at any particular library. This was a feature of another ILS that I used and was quite helpful to reduce errors.
