# References are not appearing in the correct order [duplicate]

I'm writing my thesis with the following format: My problem is that the references are not appearing in the correct, I'm having my first ref to be cited as 11 instead of 1! Although in the bibliography at the end it is shown in the correct order..

• Welcome to TeX.SE! I'm afraid it's not easy to say why your citation callouts might be out of (numeric) sequence since your code provides no \cite commands. Moreover, there seems to be a file head.tex about whose contents no information is available.

• head.tex contains the supervisors' names and date only Oct 4, 2014 at 9:25
• I am unable to replicate the problem you describe -- citation callouts not being numbered in the order they occur in the document -- using just the code you've provided. Please provide a real MWE that generates the problem behavior you say you're encountering. Please attempt to make the example code minimal, in the sense that you don't load all kinds of packages that are not relevant for the problem at hand. If any \cite commands occur inside \caption or \section-type commands, please be sure to mention this fact.

• Yes, I have so many references inside captions, tables and of course sections and chapters. The list of figures and tables references start from 1 and ends at 10 and then the first reference in the paragraph starts by 11. So I tried removing the \listoffigures and \listoftables and then the ref appeared in the correct order! Oct 4, 2014 at 16:31
• But now how can I add both list of figures and list of tables without disturbing the order of the reference?? Any suggestions? Oct 4, 2014 at 16:44
