Be careful, just because a book is no longer readily available does not mean that one can ignore the copyright.
Correct, though it becomes kind of a moment 22 then. I have a friend who's a recording artist, he's got the same trouble. There's a range of discs he did during the 90's that are no longer available, but he's under contract with Sony, and they don't want to print more of em, but his fans are asking for them. We were discussing this and even talked about spreading the material online as it was a dead end no matter what (Sony did not even allow him to make a series of prints on his own etc.).
Finally we came up with the idea to get an agreement with Sony to put them on the download and streaming services, and they said yes unless there was any costs involved on their part...
Maybe this is what should be done with good old stuff like the mentioned book, e-books...
