Duplicate publication is publication of the same or nearly same work without reference to the previous publication. Duplicate publication of original work is not allowed, and a cover letter should be submitted with any submission that overlaps significantly with previously published work to notify editors. This policy does not include compilation of previously published works into a larger anthology with referencing the original publication (e.g., publishing a collection of poetry and including a previously published poem), publication of work presented in abstract or poster form, and expansion of previously published preliminary studies. If an author is including work previously published in manuscript or abstract form, those studies should be cited within the article.
