Although many of the libraries may not circulate that title, at least one (probably the U of ND) should loan to you. If you don't need the whole book and just need info on one family surname or one community, put that in your request and the owning library will copy the appropriate pages for you and send them to your library.
If you need to own a copy of the book you might try contacting the Cavalier County Historical Society to ask if they know a source for purchase of the title. Here's their website:
Cavalier County: Museum at Dresden | Dresden Museum in Cavalier County, North Dakota.
They amazingly also have a Facebook page (!) so you could probably also put a question on their page.
Osnabrock is a very cool little town. I looked it up myself to find out why all the streets are named for characters/places in The Wizard of Oz!
