The collection of Arabic papyrus, parchment, and paper at the J. Willard Marriott Library is the largest in the U.S. It contains several parchment pieces, 770 Arabic papyrus documents, and over 1,300 Arabic paper documents. The collection was compiled by Professor Atiya and his wife who purchased the collection over several years, largely from dealers in Egypt, Beirut, and London. Most of the collection originated in Egypt and the vast majority of the material is from 700 AD to the start of Ottoman rule. The collection is not yet cataloged.
