The Al-Kitaab series is a sequence of textbooks for the Arabic language published by Georgetown University Press with the full title Al-Kitaab fii Taʿallum al-ʿArabiyya (Arabic: الكِتاب في تَعَلًُم العَرَبِيّة, "The book of Arabic learning"). It is written by Kristen Brustad, Mahmoud Al-Batal, and Abbas Al-Tonsi and was first published in 1995; since that time, it has become the most popular Arabic textbook in the United States. Brustad and Al-Batal wrote the Al-Kitaab series while they were associate professors of Arabic at the University of Texas at Austin, where they taught for years. They now live in Lebanon, Al-Batal's homeland, and work at the American University of Beirut. Al-Tonsi is a senior lecturer at the Georgetown University School of Foreign Service in Qatar.
