This international workshop, hosted by the Martin Buber Society of Fellows in the Humanities at the Hebrew University, seeks to tease out and bring forth these methodological problems by raising questions such as: what makes a primary source? How do we use non-traditional sources to conduct historical research? How can historians use material culture, music, art and other non-traditional sources to work within the discipline of history? What can they learn from other scholars that traditionally work with such sources, and where do they differ from the use in disciplines such as archaeology, art history, musicology, anthropology, etc.? The workshop will contribute to a wider debate about fundamental methodological changes in History in the twenty-first century. We would also consider the flexibility of disciplinary borders and the extent to which ideas and tools from one discipline can be adopted by another.
