The records for Strijen are only available on film at a Family History Library. I wouldn't count on that though. I have a Family history Center 2 blocks away and they said they sent all their films back to Salt lake to be made digital. They do have many films that people purchased and left there though, you might want to check that out if you have a palce near where you live.
