Additions and changes
The Silesian site previously given was never completed, and has not been updated since 2000. It now points to the excellent gov.genealogy.net.
Regarding the other German-Polish links: One of them directs you to the other one. The list on the latter page is incomplete and lacks all diacritical marks. The Wikipedia list is far more accurate and extensive.GerSIG 07:11, 4 April 2008 (MDT)
