Transfer of copyright does not prevent an author from subsequently reproducing his or her article. OSA's Copyright Transfer Agreement gives authors the right to publish the article or chapter in a compilation of the author's own works or reproduce the article for teaching purposes on a short-term basis. The author may also publish the article on his or her own noncommercial web page ("noncommercial" pages are defined here as those not charging for admission to the site or for downloading of material while on the site). In addition, we allow authors to post their manuscripts on the Cornell University Library's arXiv site prior to submission to OSA's journals.
