About NYPL Digital Collections

The New York Public Library Digital Collections contains 719,398 items and counting. While that is a small fraction of the Library's overall holdings, it is representative of the diversity of our vast collections—from books to videos, maps to manuscripts, illustrations to photos, and more.

How-To

Discover and download NYPL items spanning research subjects and historical eras.

Find Items

Looking for something? Start with a search or begin browsing by item, collection, or division. For a more extensive user guide and primer, see "NYPL Digital Collections Platform: An Introduction."

Looking for images you can reuse freely? You can browse just the items that have no known U.S. copyright restrictions. When searching, select the "Search only public domain items" option to filter your results to items with no known U.S. copyright restrictions. On the Browse page, you can easily turn this filter on and off with the “Show Only Public Domain” button in the upper left corner of the page.

Download Items

To download, navigate to the Download Options section under each item. Simply click on your preferred file size and check your browser’s download folder for the image.

Items & Permissions

We actively review and label materials in Digital Collections with statements that indicate how you may reuse items, and what sort of permission, if any, you need to do so.

Public Domain / No Known U.S. Copyright Restrictions

To date, there are 211,057 public domain items in Digital Collections, and that number grows every day. You do not need NYPL's permission to use these items and there are no known restrictions on their use. However, these items may be subject to rights of privacy, publicity, or other restrictions depending on the format of the materials and what the items depict. It is your responsibility to respect these rights.

Though it is not required, please credit public domain items with, "From The New York Public Library," and provide a link back to each item on the Digital Collections website. Doing so helps us track how our collection is used, as well as justify releasing even more content in the future.

For more information about NYPL's public domain materials and projects, see "Free for All: NYPL Enhances Public Domain Collections for Sharing and Reuse."

Is There a Difference Between "Public Domain" & "No Known U.S. Copyright Restrictions?"

Unless you are a lawyer and/or outside of the United States, there isn't really a difference. The term "public domain" is not consistently used largely because it means different things in different places around the world. And as a U.S.-based library, NYPL limits the legal statements it makes about materials to the jurisdictions in which it operates.

But what does that really mean? When we describe the rights allowances or restrictions for a specific item in our collections, we use “no known U.S. copyright restrictions." However, when we are speaking more generally—on our websites, blog posts, and in other modes of communication with users—we often use "public domain," by which we mean the aggregate collection of items we offer to the public without copyright restrictions on reuse.

Copyright Held or Managed by The New York Public Library

NYPL holds or manages copyright for some items. If you need information about reusing these items, please contact Permissions and Reproductions.

Copyright Status Undefined

Not all Digital Collections items have been formally reviewed for copyright status. For unmarked items, we do not grant or deny permission for reuse. You may want to look into resources that can help you determine on your own whether the items are in the public domain—and therefore free of copyright restrictions—including "How to Investigate the Copyright Status of a Work [PDF]" from the United States Copyright Office and the public domain determination chart made available by the Cornell Copyright Information Center.

If materials are not in the public domain, it is your responsibility to determine and satisfy copyright or other use restrictions when publishing or otherwise using the materials. You are solely responsible for determining whether your use of any digital object requires the permission of any other person or entity, or determining whether you can exercise fair use rights. You can learn more about fair use on Wikipedia, or review fair use basics and a fair use checklist from Columbia University’s Copyright Advisory Office.

Meanwhile, every day we review and update the copyright status of Digital Collections items. At this time, we are not able to take requests about which items are at the top of our queue for review. If you need more information about reusing items in Digital Collections, please contact Permissions and Reproductions.

Data

Digital Collections is at the core of NYPL's efforts to enable new uses of items, collections, and data.

Linked Projects

Whenever possible, we link items in Digital Collections to other places where you may be able to find out more about them. Some of the places we link to include the NYPL Catalog, NYPL Archives Portal, and Digital Public Library of America.

Meanwhile, we also extract data from historical sources and materials, and have incorporated links to those data extraction experiments wherever possible. Some of those projects include Map Warper, Building Inspector, Stereogranimator, and What's on the Menu.

Available Metadata

NYPL metadata published via the sources below is released under a Creative Commons CC0 1.0 Universal Public Domain Dedication.

Digital Collections metadata records are also available for bulk download via the Digital Public Library of America (DPLA). This includes all publicly available record descriptions for items on this site. The metadata standard we use is MODS, and the bulk data offered through DPLA is stored in JSON. The bulk download data is refreshed roughly every other month.

Platform

NYPL uses Fedora Commons software for our repository, while our bibliographic, technical, and rights metadata is managed by a custom Ruby on Rails app we call—appropriately enough—the Metadata Management System. The Digital Collections platform itself is also a Rails application, but uses a lot of JavaScript (including libraries such as the Internet Archive's BookReader).
