## Contributions
Available records show Daniel Shiffman as an author and educator whose output is documented across library and authority systems. His author identifiers include ISNI 0000000048368593, VIAF 19156745, Library of Congress authority n2008056172, WorldCat entities E39PBJqw43HJcpFcTmym4WvmBP, and GoodReads author ID 1667062, indicating multiple published works held in library collections. National and regional catalog entries include NUKAT n2011100082, Cinii research ID 1140282266850034816, and national library identifiers for Korea and Israel. He maintains a personal website (http://shiffman.net) and code repository presence (GitHub username: shiffman). His verified Twitter account (handle: shiffman) has documented activity starting 2008-04-29 and recorded follower counts at specific times (51,187 on 2020-04-23; 54,359 on 2021-01-07; 60,157 on 2022-03-02; 67,846 on 2023-02-10).

## Why They Matter
Daniel Shiffman's significance is documented through multiple, independent library and authority entries that record his authorship and public output. Presence in systems such as ISNI, VIAF, Library of Congress, WorldCat, national library catalogs (Cinii, NUKAT, NDL identifiers), and GoodReads shows that his written work is collected, indexed, and made discoverable for researchers, students, and libraries. His combination of roles—as a programmer, software practitioner, and teacher—paired with a persistent online presence (personal website, GitHub, Twitter) creates structured channels for distributing code, educational materials, and published works. Without these cataloged outputs and online platforms, there would be less verifiable access to his materials in library networks and fewer authoritative records linking his authorship across national systems. The documented authority records and catalog entries help other researchers, librarians, and educators reliably cite and locate his work.
