Collection of manuscripts of Khoja Ahmed Yasawi and his student Suleiman Bakyrgani
The National Library of the Republic of Kazakhstan houses a collection of manuscripts of Khoja Ahmed Yasawi (1103-1166) and his follower Suleiman Bakyrgani (1091-1186). All manuscripts are in the medieval Turkic (Chagatai) language and contain about 1,400 pages. This collection includes monuments of medieval Turkic literature, which, according to Yasawi experts, have no analogues in the world. The collection contains information on the history, culture, literature, and ethnography of the Turkic peoples in the context of the entire Turkic civilization. The collection of the documentary heritage of Yasawi and his students had a great influence on the development of the spiritual culture of the ancient Turks and contributed to the development of the Turkic language and literature. This collection includes the manuscripts of H.A. Yasawi “Risala” (“Mirat-ul-qulub”) (16th – 17th centuries), “Nasabnama” (Genealogy) (1687-88), “Diwani Hikmet” (1834) and “Hikmat Hazrat” (18th century), Suleiman Bakyrgani’s manuscript “Hikmat Hazrat Sultan al-Garifin” (16th century).

International Anti-Nuclear Movement “Nevada-Semipalatinsk”
The documentary heritage is a single collection of documents related to the actions of the International Anti-Nuclear Movement (IAM) “Nevada-Semipalatinsk”, which put an end to nuclear weapons testing at the Semipalatinsk test site, which caused enormous harm to the environment and the gene pool of the people of Kazakhstan. The collection is stored in two archives of the Republic of Kazakhstan – the Central State Archive of the Republic of Kazakhstan (CSA RK) and the State Archive of Film, Photo and Sound Recordings. MAD "Nevada-Semipalatinsk" was the first anti-nuclear non-governmental organization (NGO), created in 1989 in the territory of the former USSR as a natural need of life, aimed at protecting humanity from the general nuclear danger. Its goal was to destroy all nuclear test sites in Kazakhstan, create public control over industrial waste, create an ecological map of the region. The movement has a Charter, organizational structure and cultural symbols. For more than 40 years since August 1949, the steppes of Kazakhstan were a test site, uranium processing centers and burial sites for nuclear technological waste. To summarize, it can be said that the total impact of nuclear explosions in Kazakhstan exceeds the power of the nuclear bomb dropped on Hiroshima by 45 thousand. As scientific research shows, in Kazakhstan about 2.6 million people have become victims of genetic mutation as a result of long-term exposure to radiation. The movement put on the agenda: 
* organizing actions aimed at a complete ban on nuclear tests, prohibition of nuclear, missile and other types of weapons of mass destruction, illegal disposal of radioactive and toxic waste;
* protection and revival of nature, man, culture; 
* protection of human rights; 
* solving environmental problems at the national and international levels. 
Nevada-Semipalatinsk played a positive role in raising awareness among the general public of the need to combat the nuclear threat. It received wide support throughout the world and became a real historical factor in solving global environmental problems.

Archival documents of the Aral Sea
The main criteria for selecting the Aral Sea Archival Fund from the Central State Archives of the Republic of Kazakhstan (CSA RK) were its uniqueness and significance in the context of the global environmental situation. The environmental consequences for the Aral Sea and the adjacent vast region of Central Asia and Kazakhstan are one of the largest man-made disasters in the world. The fall in sea level and its gradual disappearance due to intensive use for irrigation of vast areas of cotton and rice cultivation, the Amu Darya and Syr Darya rivers flowing into the Aral Sea, led to abrupt climate changes in the region and the occurrence of salt storms. As a result, the disappearance of local flora and fauna, the deterioration of the fishing industry, the impact on the health and socio-economic status of the population of the region were the results. It has now been proven that climate change in the Aral Sea region and the occurrence of salt storms have had a negative impact on the environmental situation in the world. Since this is not a problem of one region or country, but an international problem, scientists from different fields and public figures of the world community are looking for solutions to revive the sea. The available documents are the only source for traditional and applied research and for the implementation of measures aimed at reviving the ecological and socio-economic development of the region.
