The Malik National Museum of Iran was opened by Haj Hossein Aqa Malek in 1937 and then along with other properties was endowed to Astan-e Qods-e Razavi. This library is the first endowed-private museum in Iran and also is one of six grand libraries of the country whose main concentration is on manuscripts and is located in Tehran. Paving the way for recording Haj Hussein Aqa-Malik’s deed of endowment in the UNESCO’S Memory of the World Programme through signing a MOU between Malik National Museum and Library and National Library and Archives of Iran (NLAI) was emphasized. “Haj Hossein Aqa Malek in the deed of endowment, which had been compiled and registered in 1937, has considered very meticulously every aspects of the endowment and has set rules and standards for each aspect. He even has determined how researchers should use books, how employees must be insured, how manuscripts and historical materials must be purchased and how his endowment must be supervised, as such subtlety and worldview of him in compiling the deed of endowment has brought about a special and exemplary position for this important historical deed among other available deed of endowments”, Mahdi Yasavoli, the director of Public Relations of Malik National Museum and Library, said. “Hence, recording it in the UNESCO’s Memory of World Program, with management and follow-ups of NLAI, would pave the way for keeping and introducing this deed to the world as an advanced and standard deed of endowment.
