I donβt mean to distribute, but to scan for myself to read digitally, am I allowed to do that legally and ethically when I buy a physical book or would that be totally unethical and illegal?
I believe the distinction is you have a right to copy for own use/backup but you donβt have the right to break the DRM preventing you from doing so.
For example, you have a right to make a copy of a video game (by installing it to hard drive) but DRM willl prevent you from running it unless you have the original disk in the drive.
