1992年,蓝丽蓉出版了她的代表作:《雪泥鸿爪溯数源》(Fleeting Footsteps, Tracing the Concept of Arithmetic and Algebra in Ancient China)[2]。她在书中详述中国五世纪《孙子算经》的十进位制筹算的记数法则、和加、减、乘、除、分数运算、开平方运算的程序,还详细比较九至十世纪阿拉伯著名数学家花拉子米、伊本·拉班关于印度算法的多种著作,发现阿拉伯国家早期关于印度算法中的四则运算和开平方方的程序,和孙子算经中的方法十足相同,从而提出印度-阿拉伯数字系统的十进位制概念,乃起源于中国算筹的学说。她说,她之所以能够做出这个跨文明的重要发现,乃因以往西方数学史家不通中算史的中文文献,而中国中算史家又不容易取得西方图书馆的文献,而她自己则中西文献可以兼而得之之故。《雪泥鸿爪溯数源》一书在2004年再版,其本内容大致和92年版相同,但增加一篇她在2002年在北京召开的国际数学史大会上,在荣获凯尼斯·梅奖之后的致谢演讲,题为《中国古代的数学及其对世界数学的影响》(Ancient Chinese Mathematics and its influence on World Mathematics)作为代序,和著名数学史家 Joseph Dauben 的引言。
