The New York Public Library opened an online archives portal. From their press release:
“Today we are proud to announce that out-of-copyright materials in NYPL Digital Collections are now available as high-resolution downloads. No permission required, no hoops to jump through: just go forth and reuse!
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. Online users of the NYPL Digital Collections website will find more prominent download links and filters highlighting restriction-free content; while more technically inclined users will also benefit from updates to the Digital Collections API enabling bulk use and analysis, as well as data exports and utilities posted to NYPL’s GitHub account.”
