Anna's Archive

Anna's Archive is a search engine for shadow libraries created by the pseudonymous Anna. It was founded in direct response to law enforcement efforts to close down Z-Library in 2022. It describes itself as a project that aims to "catalog all the books in existence" and to "track humanity's progress toward making all these books easily available in digital form".

Anna's Archive mirrors Library Genesis, Open Library, Sci-Hub and Z-Library, and has scraped (downloaded the entirety of) the library catalog WorldCat and the scanned book database Duxiu. Anna's Archive says that it does not host copyrighted materials and that it only indexes metadata that is already publicly available.

As of 2024-07-01, Anna's Archive includes 30,445,640 books and 100,357,126 papers.

History
Anna's Archive was founded by the Pirate Library Mirror, a team of anonymous archivists, in direct response to law enforcement efforts to close down Z-Library in 2022.

On 2023-10-03, Anna's Archive was reported to have scraped WorldCat, the world's largest book metadata database. Anna's Archive says that the scrape "marks a major milestone in mapping out all the books in the world" and that it allows them to "work on making a to-do list of all the books that still need to be preserved". In response to the scrape, Anna's Archive was sued on 2024-01-12 by OCLC, one of the maintainers of WorldCat. OCLC says that the scrape was the result of cyberattacks on its servers and that Anna's Archive allows public download of scraped data. The only named defendant in the lawsuit denies any involvement with Anna's Archive or in hacking WorldCat.

On 2023-11-04, Anna reported on their blog that they had acquired a copy of Duxiu, a database of scanned Chinese books. The data was released without embargoes on June 16 2024.

On January 2024, Anna's Archive was blocked in Italy due to a copyright complaint by the Italian Publishers Association. On March 2024, Anna's Archive was blocked by some internet service providers in the Netherlands due to a request by BREIN, an anti-piracy group.

On 2024-07-01, the  mirror started to redirect to the   mirror. On 2024-07-11, Anna reported on their subreddit that the  mirror was not functioning, and to use the   mirror, or the new   mirror instead; the   mirror also stopped redirecting.
