Now, in 2026, we're acting like cloning a published book is not technically feasible? That doesn't track. With publishing on-demand, it's easy to imagine a business with digital copies of all these works that they make available for print-on-demand.
The uncomfortable reality is that most of these books are nothing anyone cares about. Even the book sellers in the 404 story call them dead inventory.
Can we get some actual book titles into the discussion so we can focus on facts rather than speculation?
Op means a lot of those books were made before computers were used for that purpose and the publishers and probably authors no longer exist, so there is no digital copy to just reprint, unless someone scans it themselves and publishes it, risking copyright violation when done at large scale due to possible exceptions to this rule
Did they? Then why did they "don't want anyone to know about this"? Or do you think their lawyers are dumb?
Who is going to claim a copyright violation?
Most developed countries have a 'legal deposit' system with a national archive/national library that requires publishers to send a copy of their works to them. They've existed in some form for centuries in some countries.
