During the late 1920s, early 1930s, and 1990s the Library of Congress acquired a large collection of Arabic script calligraphy sheets. This collection presents 373 Arabic calligraphy sheets, ranging from the 9th to the 19th centuries, including examples of calligraphic art - illuminated panels, albums, and poems. In addition to individual calligraphy sheets, the presentation has essays on Ottoman and Persian calligraphic styles, an in-depth look at Qur'anic calligraphic fragments, and an essay discussing some of the Library's notable Arabic script calligraphy sheets and illuminations.
