Self-plagiarism is using your previously published work (either a paper you handed in for a class or published as a book, book chapter, article, etc.) without citing that source.
Self-plagiarism can be categorized in two ways: recycling or salami slicing. The provided table provides more information about each.
| Recycling | ||
| Data | Data Augmentation | Combining old data with new supporting data and representing as a new study. |
| Duplicate Publication | Essentially the same article or book chapter published in two different publications. | |
| Redundant Publication | Using previously published data (with or without new data) | |
| Text | Re-use of published text in a new publication | |
| Salami Slicing | ||
| LPU: Least Publishable Unit | Using different results in separate papers when those results are best presented together. | |
