[Koha] Adding Item Types

Good day all, I am trying to add item types. I am getting stymied at the authorized value. What am I look for to put into this blank? Is it where my current MARC record holds this information? I haven't separated out my collection to that point before now so my current MARC values don't divide it like this. Any input is will help.
