Even though this paper is from 2007, we thought the discussion about text-recycling was excellent enough and incredibly useful, so we thought we’d share it.
Self-plagiarism raises knotty conceptual, legal, ethical, and theoretical questions. This essay provides an extended definition of self-plagiarism, re- views the case law regarding self-plagiarism in copyright infringement, examines the ethics of self-plagiarism, considers self-plagiarism relative to post-modern critiques of authorship and originality, and concludes, finally, that we do and should give writers legal and ethical latitude for limited self-copying, although certainly not for egregious duplication. This leeway for authors fits well within a more general ambivalence toward plagiarism, an uneasiness born of definitional, moral, and theoretical uncertainty.
