I recently became the co-author of a working paper an older version of which is online (at which stage I was not a co-author yet).
We added and changed most of the content, however some applications remained virtually unchanged. How do I need to cite/reference the earlier version of this paper to avoid plagiarism concerns? We already added "An earlier version of this paper circulated as old paper name".
I do my PhD in Germany. How do I need to cite/reference the old working paper to avoid any plagiarism concerns?
Based on the comments:
- The earlier version of the paper was not pubslished in a book/journal, but posted online on SSRN.
- I am not worried about how journals perceive an evantual submission, but merely about the (german) academic regulation(s) regarding plagiarism.
