Islamic manuscripts
Islamic manuscripts had a variety of functions ranging from Qur'anic recitation to scientific notation. These manuscripts were produced in many different ways depending on their use and period. Parchment (vellum) was a common way to produce manuscripts. Manuscript creators eventually transitioned to using paper in later centuries with the diffusion of paper-making in the Islamic empire. When Muslims encountered paper in Central Asia, its use and production spread to Iran, Iraq, Syria, Egypt, and North Africa during the 8th century.
The Al-Furqan Islamic Heritage Foundation has estimated that 3 million Islamic manuscripts have survived. Other academics talk of 7 million surviving manuscripts out of 90 million manuscripts written between the 7th and 14th centuries. The estimates vary due to several challenges, such as limited access to manuscripts located in conflict zones or held in private libraries.
