@internetarchive@mastodon.archive.org well just checked with some AI, here's the answer to my question: Any scanned work that is under copyright law that gets shared without explicit consent by publisher or authors, if the amount of sharing goes beyond fair use, then technically that is a violation of the copyright laws protecting that work, unless the author(s) died at least 70 years ago. This depends on country, but that's the case for books published in Spain. Basically, almost nothing "modern" enough can be shared legally without explicit legal approval from the copyright holders.
