The online source edition highlights central aspects of local, regional, and general German‐Jewish history providing approximately 150 digitized key documents. We consider Hamburg to be a “magnifying lens”; with reference to a tangible example, special features and characteristics will be illustrated. The source edition will be bilingual (German/ English) and mainly aimed at students and researchers, but also at schools and a general, interested, non‐professional audience. The selected sources will thereby serve as a “key” to trace major developments and central issues of German‐ Jewish history with reference to close‐by examples. German‐Jewish history is looked on within the context of general history.
