²¹ The reorganization and digitization of the Haus-, Hof- und Staatsarchiv’s Türkische Urkunden collection (TUK) is ongoing since 2023. This involved dissolving the existing archival boxes and integrating their digitized contents into the archive’s online database. There are available at https://www.archivinformationssystem.at/archivplansuche.aspx?ID=4361201 (accessed 23 February 2026). The digitization of the Turcica (Türkei I) collection is ongoing on the same platform https://www.archivinformationssystem.at/archivplansuche.aspx?ID=463 (accessed 23 February 2026). This digitization process was preceded by extensive indexing and microfilming, with a full copy available in the Hungarian National Archives.

²⁴ For example, sixty archival boxes cover the quarter century between 1567 to 1593 as opposed to only eleven boxes covering the quarter century between 1619 and 1644.

²⁵ More than half of the 441 letters published in a recent edition of the correspondence of regional governors of Buda between 1617 and 1630 are held by archives outside Vienna and Istanbul. Kármán, ed., The Correspondence. In some cases, the existence of these private collections help partly explain archival imbalances. This remains understudied on the Ottoman side, where for example, three chests full of archival documents were found in an armory in Belgrade that once formed the private archive of Grand Vizier Sarı Süleyman Pasha (d. 1687). Excerpts from these roughly 2,000 documents were translated by the interpreter Heinrich Christoph Schwegler in a bound volume from 1689 now preserved in the Wienbibliothek, Jc 82888.
