The library established in a room of the Kılıç Ali Pasha Madrasa shows some features that are not found in other libraries.
During the establishment of the madrasa, over 500 tafsir books donated by Debbağzade İbrahim Efendi were kept in a special place. In this way, the teaching personality of Debbağzade İbrahim Efendi is reflected in the library collection in a way that cannot be overlooked.
İbrahim Efendi appointed four hafizes for the library, demanding that these four to be members of his own family and that, if this is not possible, competent people from Tophane should be appointed to this task.
These four hafizes are given the task of counting the books periodically. A librarian who oversees this counting was also assigned to the madrasa.
As stated in the foundation charter of Kılıç Ali Pasha Library, and as is common in Ottoman libraries, books were not loaned out to ensure their preservation and continuity.
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.
