For some reason, in all the years that our little library has been in existence, no one has bothered to specify when a publication is primarily music notation. I'm changing this as we migrate to Koha (nearly half our stuff is music notation), but before I take the plunge I need to think about how it will work, and what it will look like. It's my understanding that Koha stores Leader information, but does nothing with it, is this correct? I want something that will show up clearly, is easily spotted. Not buried somewhere in the physical description or down in a notes field. I'm disinclined to use general material designations, but that could be one way. The other thought was item type. Collections seem less intuitive somehow, and as we have lots of special collections which might contain individual publications of music notation, I'm not sure if that works. Anyone with experience in this? Thanks -- Elaine Bradtke EFDSS
