The Felix Posen Bibliographic Project on Antisemitism comprises online databases containing more than 30,000 items on antisemitism and Holocaust. New material is added on a regular basis.·

The Databases on Antisemitism, which share a common structure and thesaurus, are:

	The Annotated Bibliography; which lists publications from 1984 to the present, providing bibliographical information and an abstract on each item
	The Retrospective Bibliography which lists publications from 1983, currently comprising books and articles published between 1960-1983.

Works on the Holocaust are included as part of the history of antisemitism in the 20th century.

The "Jewish Question" in German-Speaking Countries, 1848-1914, is a separate, unique bibliography/database. It is currently being expanded to include material of and about the period between 1914 and 1933.
