I am writing my thesis in LaTex but I have some problems with the bibliography. As always, I use the unsrt bibliography style to get the citations in order of appearance. However, this time it doesn't work so as a first citation I have the number 2 instead of the number 1.
That's the code I use:
The bibliography is in a .bib file. I also would like to add all the references I do not cite explicitly in the text. So I usually add \nocite command. It works but in the text I get [?] instead of citations.
This usually works in the past articles I wrote, I don't know why now it doesn't. Do you have any suggestions?
(I am using Overleaf)
