The Public Domain Bird Library
A curated index of canonical public-domain American bird books, with verified download links. NYC-rooted. Continuously maintained.
Most canonical American bird books from the 1870s through the late 1920s are in the public domain. They are downloadable, quotable, screenshottable, embeddable, and reissuable without permission. This is a working catalog of the books I keep coming back to as a NYC birder, with verified scans across the Internet Archive, Project Gutenberg, HathiTrust, the Biodiversity Heritage Library, and the Library of Congress. I read these to understand how the people who came before us thought about the birds we still see in Central Park. NYC and women in birdwatching first. More to come.
Books are grouped by author, then chronologically within author. Each entry: title, year, one-line note on why it matters, primary download links, and any NYC connection.
What public domain means here. Any U.S. work published before 1931 is in the public domain in 2026 (95-year rolling rule). That covers everything on this page. For the legal background, see the Cornell Copyright Term and Public Domain chart.

Published in Bird-Lore, Blue Bird, Nature and Culture, and House Beautiful, plus 20 scholarly articles in ornithological journals. Most of her substantive work was in articles, not books, but the Bird-Lore archive at the Biodiversity Heritage Library contains her writing. Her home and woodland became Birdsacre Sanctuary, opened to the public in 1960, two years after her death.
Althea Sherman (1853–1943)
Iowa naturalist (Farmersburg Township, Clayton County). Self-taught ornithologist after a teaching career. In 1915 she commissioned a 28-foot wooden tower (9 feet square, with an internal staircase, doors, and peepholes) specifically for observing Chimney Swifts; she collected 18 years of data using it, the first complete life-cycle study of the species.
