bygdebooks

I also have been trying to get the bygdebboks, from Oppland, but the librarys all say they are unavailable. We have to either buy them or go to the Universities that have them. Which for a lot of people, which I am one of, cannot do. So is there any other way to get this information and where and how much are these books? My husbands family are from 5 of the 6 areas of Oppland and would probably cost a fortune to aquire all books. Would appreciate any input on this subject. Thanks Lee
