1. Some of the contents of a book I have borrowed are out of copyright (the copyright period has expired). If I photocopy only the pages containing those contents, will I still infringe the copyright for the book?

Yes, because apart from the copyright of the contents of a book, there is also a copyright for the typographical arrangement of the book. Photocopying the pages of a book reproduces not only the contents of the pages, but also their layout, that is, the typographical arrangement of the book. Thus although it is perfectly legal to photocopy works or contents out of copyright, you may still infringe the copyright for the typographical arrangement of the book, which belongs to the publisher. This is so unless your act falls within the permitted acts as explained in section B.
