I can't say a KH library serves much purpose anymore, if it ever did. I could see it being discontinued
My father had in his possession some of the local congregation's correspondence dating to the '40s when the congregation was formed, like the letters that established the congregation, etc. I thought it was pretty interesting at the time, and that it should be kept for interest and local history. But none of the young elders wanted the stuff around, and I think it was eventually thrown away.
