I will note however, that there is a "fair use" exemption, and that applies to copying materials for the purposes of criticism and reviews ( such as a newspaper or magazine book review), private study and academic use, and for an archive to manage its collection - for example to make a copy available to be read if an original book is too fragile to be handled.Note: There is no distinction made above with respect to "personal" versus "commercial" use.
As always, there are guidelines and rules around these uses.
