GenealogyIndexer.org is a free website for searching 2 million+ pages of historical European directories (business, address, telephone), yizkor books, Galician secondary school reports, military documents, and more. Containing many millions of personal names – often with towns, street addresses, and occupations, and sometimes with birth dates, maiden names, or patronymics – most of the 4,000+ sources are not searchable elsewhere. This talk will provide an overview of all sources, highlighting recent additions, and will demonstrate various search techniques. The use of directories in the Warsaw property restitution process will also be discussed briefly.
