These documents, which are examples of primary sources on the last period of the Ottoman Empire and the early years of the Republic through the eyes of the Ebüzziya family, a family of journalists, are divided into two groups: the Ebüzziya family and Ziyad Ebüzziya. The first group of documents begins with journalist, writer, publisher, and calligrapher Ebüzziya Mehmed Tevfik and continues with his sons Talha Ebüzziya and Velid Ebüzziya. Featuring correspondence with late Ottoman intellectuals, such as Ali Suâvi, Server İskit, Yunus Nadi, Recāizāde Mahmud Ekrem, family correspondence, articles published in the newspaper Tasvîr-i Efkâr, numerous works printed at Matbaa-yı Ebüzziyâ, and works with arabesque decorations, the document group contains valuable documents and information that shed light on the last period of the Ottoman Empire. The second document group consists of the correspondence of Ziyad Ebüzziya, the grandson of Ebüzziya Mehmed Tevfik, who lived in the Republican period, with the prominent figures of the period, in addition to calendars, postcard samples, and more. They were printed at Ebüzziya Printing House and constitute a private collection. The collection contains a wealth of material such as photographs, engravings, maps, and newspaper clippings.
