3x new books added to the Pirate Library Mirror (+24TB, 3.8 million
books)

annas-blog.org, 2022-09-25

In the original release of the Pirate Library Mirror, we made a
mirror of Z-Library, a large illegal book collection. As a reminder,
this is what we wrote in that original blog post:

    Z-Library is a popular (and illegal) library. They have taken the
    Library Genesis collection and made it easily searchable. On top
    of that, they have become very effective at solliciting new book
    contributions, by incentivizing contributing users with various
    perks. They currently do not contribute these new books back to
    Library Genesis. And unlike Library Genesis, they do not make
    their collection easily mirrorable, which prevents wide
    preservation. This is important to their business model, since
    they charge money for accessing their collection in bulk (more
    than 10 books per day).

    We do not make moral judgements about charging money for bulk
    access to an illegal book collection. It is beyond a doubt that
    the Z-Library has been successful in expanding access to
    knowledge, and sourcing more books. We are simply here to do our
    part: ensuring the long-term preservation of this private
    collection.

That collection dated back to mid-2021. In the meantime, the
Z-Library has been growing at a staggering rate: they have added
about 3.8 million new books. There are some duplicates in there,
sure, but the majority of it seems to be legitimately new books, or
higher quality scans of previously submitted books. This is in large
part because of the increased number of volunteer moderators at the
Z-Library, and their bulk-upload system with deduplication. We would
like to congratulate them on these achievements.

We are happy to announce that we have gotten all books that were
added to the Z-Library between our last mirror and August 2022. We
have also gone back and scraped some books that we missed the first
time around. All in all, this new collection is about 24TB, which is
much bigger than the last one (7TB). Our mirror is now 31TB in total.
Again, we deduplicated against Library Genesis, since there are
already torrents available for that collection.

Please go to the Pirate Library Mirror to check out the new
collection. There is more information there about how the files are
structured, and what has changed since last time. We won't link to it
from here, since this is just a blog website that doesn't host any
illegal materials.

Since last time, we have gotten a lot of suggestions and ideas for
collections to mirror, which we would love to spend more time on.
We're not doing this for money, but we would love to quit our jobs in
finance and tech, and work on this full time. Last time we only got a
single donation of $35 (thank you!), and we would need a lot more to
subsist. If you too think it's important to preserve humanity's
knowledge and culturual legacy, and you're in a good financial
position, please consider supporting us. Currently we're taking
donations in BTC: 14RVdnhpZNffJuAWXenmfHLHQxCvBtHdGM. We really
appreciate it.

Of course, seeding is also a great way to help us out. Thanks
everyone who is seeding our previous set of torrents. We're grateful
for the positive response, and happy that there are so many people
who care about preservation of knowledge and culture in this unusual
way.
