紐約公共圖書館這次放出了十八萬張數位資料，包括歷史照片、地圖以及信件：「The New York Public Library Lets You Download 180,000 Images in High Resolution: Historic Photographs, Maps, Letters & More」，圖書館官方的公告在「Free for All: NYPL Enhances Public Domain Collections For Sharing and Reuse」這邊：
The release of more than 180,000 digitized items represents both a simplification and an enhancement of digital access to a trove of unique and rare materials: a removal of administration fees and processes from public domain content, and also improvements to interfaces — popular and technical — to the digital assets themselves.
除了可以在「NYPL Digital Collections」這邊搜尋下載外，還有 API 可以用：「The New York Public Library Digital Collections API」，在 GitHub 上也有工具可以使用：「Digital Collections Public Domain Item Data and Tools」。
而且這 18 萬張資料是完全的開放，不需要事先取得館方授權：
No permission required, no hoops to jump through: just go forth and reuse!
將 public domain 的文物數位化，傳遞與保存變的更便利... (也讓做研究的人更容易取得資料)
