When Ignaz Goldziher passed away on November 13, 1921, he left behind a corpus of scientific correspondence of over 13,000 letters from about 1,650 persons, in ten languages. His Nachlass, including the letters as well as his hand-written notes and works, was bequeathed to the Hungarian Academy of Sciences. The corpus, which is freely accessible in its entirety in digital form \footnote{konyvtar.mta.hu and amirmideast.blogspot.com} constitutes the single most important source informing about the history of Arabic, Jewish, and Islamic studies and cognate fields during Goldziher‘s time. Selected portions of the Goldziher correspondence are available in critical editions, while other portions have been consulted for studies on the history of the field, but the bulk of the material has as yet remained untapped. This inventory aims to provide an overview of those parts of the correspondence which are available in publication, as well as of studies based on the correspondence.
