Comment on Did Dr. Krashen Commit Self-Plagiarism? by moom

I’m thinking it is likely that standards are different in the humanities and in social and natural sciences. I read on the Chronicle Fora that it is considered bad to give the same paper at seminars and conferences multiple times. By contrast, in economics it is highly recommended that in order to prepare a paper for journal submission you should present it in as many fora as possible and get comments to improve your paper. Similarly, including introductory material or methods detail in more than one paper is acceptable as long as each journal article also present substantial new results and/or data.
