Derdest defterlerinin kaynak degeri üzerine bir deneme: 493 numaralı ayntâb derdest defteri'nin analizi

Derdest registers were registers which showed who was in control of the timar income. These registers, which contain important data about the Ottoman timar system, gave information about timar types, the places constituting the timar income and their incomes, how many shares they possessed, the name of dirlik owners, their jobs and qualities, the date of their certificates and even their photographic (pictorial) appearances. This article moves from all the mentioned data and applies a methodological test on the value source that Derdest registers possess concerning the Ottoman timar system and its socioeconomic history using the Ayi{dotless}ntab derdest register, numbered 493 as an example.
