XVI. yüzyılda Kütahya Sancağı'ndaki yerleşme merkezlerini tapu-tahrir defterlerinde bulmak mümkündür. 1534 tarihlerindeki defterlerdeki bilgilere göre, Kütahya Sancağı'nda 10 nefs-i şehir, 2 kasaba, 4'ü gebran 1'i yahudi olmak üzere toplam 91 mahalle, 1071 köy ve 274 mezraa bulunmaktadır.

The Public Library of the Manisa Province has a fairly rich collection of medical manunscripts some of which are unique copies. Two examples that may be cited in this connection are Tarvih al-Ervah by physician and poet Ahmedî (1334(?)-1413) and the Persian translation of Beyrunî's Kitab-al-Saydala. Another unique manuscript is an abridged translation of Zahravî's work, which I intend to introduce here briefly.
