I want to say that you don't know what books are worth reading until after at least 1000 years, but actually all books are worth reading after 1000 years. They become tsukumogami, somehow old and wise even if they started dumb. The list of the garbage from the 16th and 17th century I've spent all day reading that is exactly their equivalent of the self-published AI slop novel is embarrassingly long.
If there are already good pirated copies of it, cut the spines anyway and you can use the pages for fill when you're packing things. Lots of O'Reilly in my life went that way.
edit: the problem is having access to a indy print shop that will scan them for you (it only takes a few minutes, but the machine is huge and expensive.) Most of them are closed down and have been replaced with chains. I was spoiled for a while working with one.
