While working on my bachelor thesis I came across the challenge of having to reference all papers I used as references. For this, I used BibTex as it was a requirement. I had completed the whole BibTeX file and added a reference section in my latex document. However, I did not see a single entry in the reference section. I used to think that the problem was in the BibTeX file and tried changing all parameters, but nothing seemed to help.
The actual problem was that I still had not cited any of the papers in my document. Only after adding a citation the paper references will be shown in the references section.
