Self plagiarism is a unique type of plagiarism. Self-plagiarism is when an author reuses or recycles content that has already been published. The content can be either data or written text. The table below shows the different ways how self-plagiarism can occur (content from Stephen Gilliver).
|
Recycling |
||
| Data | Data Augmentation | Old data with new supporting data presented as a new study. |
| Duplicate Publication | Essentially the paper or article published in two different journals. | |
| Redundant Publication | Previously published data (with or without new data). | |
| Text | Reuse of published text in a new publication. | |
| Salami Slicing | ||
| LPU: Least Publishable Unit |
Different results as separate papers when best presented together. | |
