Print them how? Am I supposed to type up all the pages of that falling apart book - book scanning helps but still requires extensive effort? What about the page that got ripped out and is missing, how do I recreate that?
While it is likely legal for me to go through all that effort for myself, it isn't legal for me to share the fruits of my effort with someone else who wants a copy so they need to do it themself. Even if they have a worn out copy themself it isn't clear that I can print them a new copy. If I want to share this work with someone else who might want it I'm stuck - I can only do the above for personal use.
