The heart of Qatar National Library, the Heritage Library is a unique contribution to Qatar’s cultural landscape. Its growing collection includes rare and valuable archival documents, books and periodicals in various European languages; early Arabic printed materials, such as books, journals, magazines and newspapers; and Arabic manuscripts, maps, atlases, globes, historical photographs, and instruments and tools related to travel. A number of the printed materials date back to the 15th century, when the printing process had recently been introduced in Europe, and these antiquarian books are among the rarest and most valuable features of the Heritage Library's collection.

QNL is a community space that helps facilitate the effective exchange of ideas and communal learning.Tools and equipment are provided at Innovation Stations, catering to a vast array of activities and interests – videography, photography, design, sound editing and 3D printing, and much more. A music studio and STEM-focused resources further promote learning through doing. With an avowed focus on preserving important cultural and historical items, QNL contains a dedicated Conservation and Preservation Laboratory which restores items in the Heritage Library, whilst climate-controlled display cases help preserve them. The Digitization Laboratory digitizes items from QNL and other collections, making them available to scholars worldwide. 

Qatar National Library's state-of-the-art building is located in the heart of Education City, Doha. Unlike any other place in Qatar, Education City is home to branch campuses of some of the world’s leading educational institutes, a homegrown research university, start-up incubators, technology parks, heritage sites, cultural institutions, and much more.
