1992年,藍麗蓉出版了她的代表作:《雪泥鴻爪朔數源》(Fleeting Footsteps, Tracing the Concept of Arithmetic and Algebra in Ancient China)。她在書中詳述中國五世紀《孫子算經》的十進位制籌算的記數法則、和加、減、乘、除、分數運算、開平方運算的程式,還詳細比較九至十世紀阿拉伯著名數學家花拉子米、伊本·拉班關於印度算法的多種著作,發現阿拉伯國家早期關於印度算法中的四則運算和開平方方的程式,和孫子算經中的方法十足相同,從而提出印度-阿拉伯數字系統的十進位制概念,乃起源於中國算籌的學說她說,她之所以能夠做出這個跨文明的重要發現,乃因以往西方數學史家不通中算史的中文文獻,而中國中算史家又不容易取得西方圖書館的文獻,而她自己則中西文獻可以兼而得之之故。《雪泥鴻爪朔數源》一書在2004年再版,其本內容大致和92年版相同,但增加一篇她在2002年在北京召開的國際數學史大會上,在榮獲凱尼斯·梅獎之後的致謝演講,題為《中國古代的數學及其對世界數學的影響》(Ancient Chinese Mathematics and its influence on World Mathematics)作為代序,和著名數學史家 Joseph Dauben 的引言。Fleeting Footsteps
