The tradition of "worship in the library", which we can hardly see in 16th-century libraries, was also practiced in the Kılıç Ali Pasha Library.
Among the duties of the hafizes in the madrasa were praying and reading the Qur'an every morning when the library was opened. The library, which contains over a thousand works, had been offered to the service of the readers in a room of the Kılıç Ali Pasha Madrasa for a long time.
During World War I, like many other libraries, it was transferred to the Sultan Selim Library (1914) and then to the Süleymaniye Library (1918) and kept there. After the latest restoration of the madrasa, the library continues to be used as a library in accordance with its original form.
