The building was overhauled by the project of architects Sadikh Dadashov and Mikayil Huseynov, who placed sculptures in the façade and reconstructed two floors.

During World War II, when the 800th anniversary of the Persian poet Nizami Ganjavi was celebrated in Leningrad Blockade, the placement work of the museum's exposition was continued.

[10] Further renovations took place in summer 2005, after a visit of Ilham Aliyev, the president of Azerbaijan, the previous year.

There are more than 3000 manuscripts, rare books, illustrations, portraits, sculptures, miniatures, memories of poets and other exhibits in 30 general and 10 auxiliary halls of the museum.

[15] The museum's most well-known exhibits include a manuscript of Nizami's Eskandar Nameh in Persian language, which was written in 1413; a manuscript of Fuzuli's “Bangu Bada” (1569); and “The Eastern poem about Pushkin’s decease” of Mirza Fatali Akhundov.
