LaTeX Warning: Citation `' on page 2 undefined on input line 131.

Post by Nadia »

Dear all,

My Latex file was working correctly. Yesterday, when I opened it again to add something I realised that some references are not in the PDF file however they are there in bib file. Could you please help with this.

Best regards,
Nadia

NEW: TikZ book now 40% off at Amazon.com for a short time.

And: Currently, Packt sells ebooks for $4.99 each if you buy 5 of their over 1000 ebooks. If you choose only a single one, $9.99. How about combining 3 LaTeX books with Python, gnuplot, mathplotlib, Matlab, ChatGPT or other AI books? Epub and PDF. Bundle (3 books, add more for higher discount): https://packt.link/MDH5p

We would need to see a minimal working example to help you properly. Please see the section how to get help in the latex wikibook.
The smart way: Calm down and take a deep breath, read posts and provided links attentively, try to understand and ask if necessary.

Hi Nadja,

here's a link describing what Johannes means: Infominimal working example.
For now, I just think you have a citation in the text that is not in the .bib file.

Thanks a lot Johannes_B for your reply. I did sort it out. There was one bracket } missing. The missed bracket has caused disappearing 5 references.
