No one lives in vacuum. One question was raised recently by a friend about his immigrant ancestor. His own personal brick wall. It turns out that this particular ancestor is Norwegian and immigrated in the latter part of the 1800s. Knowing the extent of genealogical records from Norway and other Scandinavian countries, I expressed surprised at his dilemma. To him, the Norwegian immigrant was a brick wall, to me, the immigrant was immediately a window screen. He was focusing on the screen, I immediately focused on the world beyond.
As an example of the world beyond the screen, especially for Norway, I would refer you to the FamilySearch Research Wiki on Norway. Reviewing the resources offered, gives a really good example of seeing beyond the screen with the Sogn og Fjordane Fylkeskommune -- Fylkesarkivet website. As the site says:
Fylkesarkivet also offers many other entry ways to local history – through themes and organized resources from the following domains:Do you see what I mean by looking beyond the screen? And what's more important nearly all of the Norwegian records are free online (i.e. not yet purchased by Ancestry.com!).
• Music, film and oral tradition
• Municipal archive catalogues from the whole county
• Private archives
• Emigration to America
• Biographical and genealogical source materials
At our webpage we have organised and made available many governmental archive series which are kept in national archives. These include the oldest church registers, population censuses, census registrations, shift register, register of mortgages and land registers. In conjunction with the remainder of the historical documents such as photos, emigration records and the farm name encyclopaedia, these archive series constitute rich source materials well suited for biographical and genealogical research.

By the way, you have never seen a detailed map if you haven't looked at the Fylkesatlas Sogn og Fjordane.
