digibiblio.de a project (subsidiary) of Genealogy24.com is offering Free user registration through the end (28) of February 2014. The digitized data they offer generally consists of digitized Ahnenpässen (passports), Familienstammbüchern (family books) and GEDCOM files.
If you are looking for “a needle in the haystack”, this could afford you an unexpected/ free opportunity to search additional data. None of my family names are listed, but that doesn’t mean yours won’t be!
Viel spass beim forschen! (Have fun in the hunt!)
