Initially, the library of Haj Sheikh Mojtaba Qazvini (RAH) was constructed in the basement of Ansar Al-Mahdi Mosque (May God hasten his return) located in Koi Tolab, Mashhad, in a restricted space named Shahid Mohammad Binandeh Library. The mosque's board of trustees and Astan Quds Razavi officials made it possible for this library to be covered by this holy organisation in 1988 and was renamed Ansar Al-Mahdi Mosque Library. Due to the high number of patrons at the mentioned library and the special attention given by the late Custodian of Astan Quds Razavi to book-reading, it was decided to build a new and equipped building for both men and women. In 1993, building number one, with an infrastructure of 900 meters and three floors, was opened and began to be used. The current Custodian of AQR suggested changing the library's name to Hazrat Ayatollah Sheikh Mojtabi Qazvini (RAH), who was one of the most famous masters at the Mashhad Seminary.
The officials made the decision to build the second phase of the library after being inspired by the unique welcome of the library's services and the people's request for the development of the library. The library's second building opened in 2001 and was available to men, but building number one was exclusively for women.
There are over 105,000 printed book volumes, over 13,500 audio book titles, and 15,800 audio- visual resources and periodicals in this library. There are currently more than 41,000 members in this library. The library is categorized into various areas, which include the open shelf study hall, reference hall, researchers' hall, press hall, book lending unit, press unit, and audio- visual resources unit for men and women.
