Monis continued to use his handwritten grammar manual, but the unavailability of any Hebrew type for printing presses required that each student copy the entire text by hand, an unpopular job which took up to a month. Monis finally persuaded Harvard to import Hebrew type from London, and in 1735, with a loan from Harvard, Bostonian Jonas Green published a thousand copies of the textbook, the first Hebrew textbook printed in North America. Monis sold the books himself out of his Cambridge home, and it was a required text for all Harvard students for the ensuing 25 years. The American Jewish Historical Society possesses two copies of the printed books, as well as one of the handwritten copies.
