1. http://metryki.genbaza.pl/. This site has digitized parish registers for many places in West Prussia. Because many of the records are transcripts of the original parish registers, the places and the parishes to which they belong do not always correspond to the Gemeindelexikon for Westpreussen. This site helps locate the correct parish to search for your place name.
