Does copyright restrict how I can adapt papers when compiling them into a thesis?
I disagree with part of the other answer, in that the copyright holder of a work is not always the creators/authors. For some journals when you publish with them and sign the licensing agreement, you transfer the copyright of your work to the publisher. Then it is up to the publisher to decide how you can reuse your paper. I would advice reviewing the copyright/licensing agreement you signed with your publisher for limitations for reuse, and if still in doubt, contact the publisher.
