NIST Digital Library of Mathematical Functions

The Digital Library of Mathematical Functions (DLMF) Project was initiated to perform a complete revision of Abramowitz and Stegun’s Handbook of Mathematical Functions with Formulas, Graphs, and Mathematical Tables, published in 1964 by the National Bureau of Standards. The DLMF Project has updated and expanded the coverage for current needs. The results have been published in book form as the NIST Handbook of Mathematical Functions, by Cambridge University Press, and disseminated in the free electronic Digital Library of Mathematical Functions.

《数学函数数字图书馆》（DLMF）项目旨在对1964年由美国国家标准局出版的、由阿布拉莫维茨和斯蒂根所著的《数学函数公式、图表与数学表格手册》进行全面的修订。该DLMF项目针对当前需求进行了更新与扩展。研究成果以书籍形式由剑桥大学出版社出版的《美国国家标准局数学函数手册》发布，并通过免费的电子《数学函数数字图书馆》进行传播。
