Just because a book is being sold on amazon, that does not automatically means that it's not in the public domain.
However, in cases where the product is not in the public domain, but is posted on the archive site, then that's pirated material.
But assuming you did block and remove all 'pirated' copies the book is out of print and the publisher and writer isn't giong to make any more money no matter how many times it is resold. (Effectively a Gamestop but with better credit)
But all media in question, are unlikely to be on an archive if they are immediately new and instead are older items. Afterall i'm sure you can find plenty of 'Pirated' copies of Windows 3.11, and we know Microsoft holds a copyright on it; But is that really something they care about, or care to enforce? How many systems still use 16bit windows? Probably a few, some ATM and older teller machines may use that type of software but it's rare.
Although i have heard of authors putting their works in the public domain when the printing is done, and the printing group refuses to let them intending to hold on to their temporary rights as long as possible even if it does nothing for them. Quite annoying.
