I'm very new to Overleaf, and I've really tried to find an answer to this but they are either not relevant or I have failed to understand. I have exported my references from Mendeley (NOT via the integration service (I'm not premium)) in BibTex format.

I have saved these as "bibliography.bib"

I have this in the preamble

\usepackage[backend=biber,style=alphabetic,sorting=ynt,citestyle=numeric]{biblatex}

\addbibresource{bibliography.bib}

and at just before the end of the document

\printbibliography

I then get no bibliography printed, and many

"You have cited something which is not included in your bibliography. Make sure that the citation (\cite{...}) has a corresponding key in your bibliography, and that both are spelled the same way."

errors that I don't understand, as they are all there, and will even autofill with \cite

I also get an error

"Package biblatex Warning: Please (re)run Biber on the file: output and rerun LaTeX afterwards."

How do I run biber on the file?

I'm incredibly lost and as this point I think I've sunk like two hours trying to fix this so I'm REALLY hoping someone can help.

I have included my entire preamble below just in case you guys can spot something a noob like me missed. - I have also included an example of one of the bibliography entries that fail to be read.

Thank you for your help :)

  • Welcome. Are you using a tool to run LaTeX like TexStudio, TexLive? – Excelsior Apr 18 at 16:41
  • Thank you :) but I have never heard of those so I assume not, I'm using it in Overleaf – Barny134 Apr 18 at 16:55

    Since you are using Overleaf you don't have to worry about running Biber. Overleaf uses the tool latexmk that automatically runs Biber for you. So your problem lies elsewhere. It can be down to roughly two things: (1) Your document errors so badly on the LaTeX run so that subsequent Biber runs are impossible. (2) The Biber run errors so badly that it does not produce usable output. Check for the first possibility first. If there is a little number in red next to the recompile button you have errors. Resolve them one by one starting from the first error. ... – moewe Apr 18 at 20:12

    ... If there are no more LaTeX errors, check for Biber errors. For this we need the .blg file. That file needs to be downloaded manually. The procedure is described in tex.stackexchange.com/q/462314/35864 for the .bbl file. You can go through the same steps to get the .blg file. The .blg file is a simple text file (no matter what your system might say), you can open it with any text editor and it is small enough that it can be uploaded in the question here. – moewe Apr 18 at 20:14

    If you want a simple test document to see how things work try gist.github.com/moewew/4e0580ae8832da44127b2a45aec02e35 (you do not need to change anything about that document, the file biblatex-examples.bib uses there is available on all systems with biblatex and will be found automatically). – moewe Apr 18 at 20:16

I tried your MWE. Try citing the bib entry as \cite{Chow}.

As you have probably noticed, Overleaf pops up a suggestion menu with the relevant bibliography entries you have in your addbibresource.

The string to be provided to cite{} is the first string inside the curly brackets of the bibliography entry, generated by Mendeley. Chow in your example.

Just to make it clearer, as another example, for this bibliography entry:

@article{Einstein1905,
    author = "Albert Einstein",
    title = "{Zur Elektrodynamik bewegter K{\"o}rper}. ({German})
    [{On} the electrodynamics of moving bodies]",
    journal = "Annalen der Physik",
    volume = "322",
    number = "10",
    pages = "891--921",
    year = "1905",
}

You should use \cite{Einstein1905}.

I hope it solves your problem.

This is not an answer. Only to help in the debugging.

Try this code. It should run twice + biber+ other two compilation, ending with no errors. You should get the output of the figure.

As you can see the Chow reference needs to be completed.

    From my experience with Overleaf, sometimes it is quicker to Clear the cache, instead of compiling the document a couple of times. – tush Apr 18 at 19:19

I had a problem similar to this 2 days ago, the reason was for my problem is that in my main.tex file i did not write the right path to my litrature.bib . I also use overleaf. I do hope this would help you
