NLAI is an educational, research, and service institution whose statute has been ratified by the Islamic Consultative Assembly (Parliament). At the highest level, it is chaired by the President of the nation.

The National Library of Iran was established in 1937. In 1979, the Tehran Book Processing Centre (TEBROC), and in 1999, the Islamic Revolution Cultural Documentation Organisation (IRCDO) were merged into the National Library. Thus, National Library and Documentation Organisation was created.

Finally, in 2002 the latter was joined by the National Iranian Archives to make NLAI. Currently, the Organisation functions in two independent buildings. One is the new building of the National Library of Iran (NLI) and the other is the building of the National Archives of Iran (NAI).
