    I have found some time ago on the forum a link to the internet where old relativity books are presented in a scanned variant. Please repeat it.

    Not necessarily. Copyrights do expire eventually. At that point the work is considered "public domain" and may be freely copied. However, in practice it is very difficult to determine if a particular copyright has expired.
