I'm planning to write my PhD thesis about the work I authored or co-authored in published journal. In this case, is it okay to simply copy and paste the paragraph from the paper to my thesis? Is this considered plagiarism if I am the author or co-author of the paper? I'm particular concerned for those papers that I'm not the first author.
