Volume 23 (part 3), dedicated to the collection of manuscripts in the Abu Rayhan Beruni Institute of Oriental Studies under the Academy of Sciences of the Republic of Uzbekistan, includes unique handwritten examples of fiction: collections of poetry, prose and folklore. The fiction of the 11th century is represented very widely and diversely. Among the masterpieces, the most important is, probably, the well-known Shahnameh (The Book of Kings) by Abu-l-Qasim Hasan ibn Ishaq at-Tusi Ferdowsi (died between 1020 and 1025). The poem was finished about 1010. The earliest copy of Shahnameh dates back to 1450, the latest to 1865. The collection contains more than 20 copies of this work. Most of them are colorfully decorated, rewritten in an elegant Nastalik script. In the treasury of the Institute there is also an outstanding work of ancient Turkic literature, Kutadgu Bilig (Blessed Knowledge) by Yusuf Balasaguni, who wrote this work in 1069 – 1070. (inv. No. 1809). In 2000, the manuscript collection of the Institute of Oriental Studies under the Academy of Sciences of the Republic of Uzbekistan was listed in the UNESCO Memory of the World program as one of the richest manuscript repositories in the world.
