Digital Library of Mathematical Functions
online project meant to be a collection of special functions

The Digital Library of Mathematical Functions (DLMF) is an online project at the National Institute of Standards and Technology (NIST) to develop a database of mathematical reference data for special functions and their applications. It is intended as an update of Abramowitz's and Stegun's Handbook of Mathematical Functions (A&S). It was published online on 7 May 2010, though some chapters appeared earlier. In the same year it appeared at Cambridge University Press under the title NIST Handbook of Mathematical Functions.
In contrast to A&S, whose initial print run was done by the U.S. Government Printing Office and was in the public domain, NIST asserts that it holds copyright to the DLMF under Title 17 USC 105 of the U.S. Code.

“Digital Library of Mathematical Functions” enters the record as online project meant to be a collection of special functions. Crown Archives preserves that source wording while asking what Digital, Library and Mathematical can confirm, complicate or overturn.
Why this record matters
“Digital Library of Mathematical Functions” is worth following because a concise public description often conceals a longer documentary argument. Here, Digital, Library and Mathematical provides the most credible route into that argument.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Dec 18, 2025. The linked authority identifier is Q24534. None of the 1 selected statements returned an explicit reference. The first chronological checks are 2010, 1998, 2007 and 1997.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
