I never saw it written with apostrophes
here is a Sami (or Saami) magazine, Baiki
http://www.baiki.org/content/links.htm

and two musicians from that culture are
Mari Boine--http://www.mariboine.no/
and Vimme--http://www.rockadillo.fi/wimme/

here is another thread on Sami culture
http://www.mudcat.org/thread.cfm?threadid=110280&messages=27

it is a misnomer to say Saami is just in norway,
as they are from a nomadic background, and their
territory stretches across Norway Sweden and Finland.
