In 1263 AH (1846–1847 AD) the Ottoman imperial government began to publish statistical and descriptive yearbooks of the Ottoman state: devlet salnames (Salname-yi Devlet-i Aliye-yi Osmaniye). Later the Ottoman provinces published their own, more detailed salnames. Salnames are often the only non-archival source for aspects of 19th and early 20th-century Ottoman history, yet they are only recently being extensively used by scholars. This article briefly describes two types of salnames and presents a union list of salnames, in the hope of increasing their accessibility and use.
