Some publishers use article-submission systems that only compile the submitted .tex file(s) in a single pdflatex or latex run—i.e., they don’t run BibTeX. In such cases, the publisher’s guidelines might ask authors (whose manuscripts use BibTeX) to paste the contents of the .bbl file into the article’s main .tex file.

This article shows two ways to access the generated .bbl file contained in your Overleaf project and provides a short video demonstrating downloading a .bbl file and pasting its content into the project’s main .tex file.

Files created during compilation are stored in the project’s cache, including any .bbl files.

1. click the file icon () beside the Recompile button;
2. scroll down and select Other logs and files;
3. a list of files in the cache is presented;

As demonstrated in the short video, comment out the line \bibliography{...} within your .tex file on Overleaf, then paste the contents of the .bbl file downloaded from the cache.

## Downloading the source, including the .bbl file

It’s also possible to download the source code with the .bbl included. Use the following steps to do that:

1. select Submit from the menu above the PDF preview window;
2. scroll down to Online Repositories;
3. locate arXiv;
4. select Submit your paper to the arXiv

5. within the pop-up window select Download project ZIP with submission files (e.g. .bbl);

6. extract the .bbl file from the downloaded ZIP file;
7. (see video) comment out the line \bibliography{...} within your .tex file on Overleaf, then paste the contents of the .bbl file.

The project is now ready to be submitted to the journal, complying with any requirements for the contents of the .bbl file to be pasted into the article’s main .tex file.
