The New York Public Library (NYPL) has released recently thousands of pics, archives and texts to be used freely. In this research fund and digital stock we can find over 700.000 images, audio, video and text files which are very rare, unique and ancient as well. All are ready-to-be-used freely.
It is sure this is not the only source, we always can have Search.creativecommons.org as a main meta-search engine to find easily different type of media free to use and with different free usage (copyleft). But nevertheless, the NYPL Digital Collections will always offer a unique variety of contents either for their historical interest, or for its ancient origin.
Explore the collection and enjoy.
