Ive found the above, although a pay site very useful in tracing my wifes ancestry.. you pay something like $12 Can. and can search for and view a number of documents..

also for Czechs there is this digital archive -
they are in the process of scanning, birth & marriage parish books going back centuries and slowly adding to the archive..
they are high quality scans but you have to know where to look
and be able to read Czech, and Latin and German help - even so you may spend a long time trying to decipher the writing..
