Agnon's writing has been the subject of extensive academic research. Many leading scholars of Hebrew literature have published books and papers on his work, among them Baruch Kurzweil, Dov Sadan, Nitza Ben-Dov, Dan Miron, Dan Laor and Alan Mintz. Agnon writes about Jewish life, but with his own unique perspective and special touch. In his Nobel acceptance speech, Agnon claimed "Some see in my books the influences of authors whose names, in my ignorance, I have not even heard, while others see the influences of poets whose names I have heard but whose writings I have not read." He went on to detail that his primary influences were the stories of the Bible. Agnon acknowledged that he was also influenced by German literature and culture, and European literature in general, which he read in German translation. A collection of essays on this subject, edited in part by Hillel Weiss, with contributions from Israeli and German scholars, was published in 2010: "Agnon and Germany: The Presence of the German World in the Writings of S.Y. Agnon". The budding Hebrew literature also influenced his works, notably that of his friend, Yosef Haim Brenner. In Germany, Agnon also spent time with the Hebraists Hayim Nahman Bialik and Ahad Ha'am.
