If you wish to submit a text that has already been published elsewhere (journal, book, report, blog), the following rules apply to republication:

If you wish to submit a text that has already been published (in a journal, book or report, or on your own or your institution’s website, or equivalent), this is republication of an article. In such cases, or if you submit a reworked version of a previously published text, this must be specified in the submission with a clear reference, and you must still have copyright or have received permission from the copyright holder.

If the text has been reworked, this should also be indicated with a reference to the original publication. In addition to quality, the editors will also evaluate the value of potential republication.
