I explain plainly what is salami silcing, a practice of fragmenting single research into as many publications as possible. Salami publishing and hazards
2. WHAT IS SALAMI SLICING
Salami is a meat product, like a sausage.
We love to slice it thinly to many pieces.
Although many slices, they are still a salami
In publication, one can create many papers from one single idea or experiment
The practice of fragmenting single research into as many publications as possible
3. SALAMI SLICING
Scientific salami slicing is the practice of fragmenting single coherent bodies of
research into as many publications as possible
An author breaks up a study into two or more smaller published articles, they are
creating “slices” of their work.
A single research is divided into “slices,” each of which is a “least publishable unit.”
Authors do it to increase their publication count, to get more recognition, to achieve
self satisfaction, to achieve faster career progression, to receive more funding
4. WHY SALAMI SLICING
The desire to publish new results rapidly.
The desire of researchers to maximize their publication count, but limited conditions
of funding and university
Publish or perish climate
Overemphasis on the size of an individual's publication record as a means of
quantifying their research output
Rewards quantity over quality.
The volume of a researcher’s publication output is a criterion on which their scientific
accomplishment is judged.

21. THE PRICE OF SALAMI SLICING
Time spent on papers that make little contribution to new scientific understanding is
time wasted.
Focus on quality, not on quantity.
If you are using data from articles that you have previously published, make sure you
cite them in your paper.
22. SALAMI SLICING
The challenge is not only to establish quantity of a researcher's scientific contribution,
but the scientific rigour and not merely numerical output.
