Overleaf Collaboration Guide

Set up and manage collaborative LaTeX projects on Overleaf with best practices for multi-author workflows, version control, and project organization.

Getting Started with Overleaf

Creating a Project

Overleaf (overleaf.com) is a browser-based LaTeX editor that provides real-time collaboration, automatic compilation, and integrated version history.

Project creation options:

Method	When to Use
Blank project	Starting from scratch
Upload project	Migrating existing local LaTeX project
Import from GitHub	Existing repo-based project
Use a template	Conference/journal submissions (IEEE, ACM, Springer, Elsevier templates available)
Copy from existing	Forking a previous project

Main File Setup

% main.tex
\documentclass[conference]{IEEEtran}  % or article, etc.
\input{preamble}  % load packages and macros

\begin{document}

\title{Your Paper Title}
\author{Author One \and Author Two \and Author Three}
\maketitle

\begin{abstract}
Your abstract here.
\end{abstract}

\input{sections/01-introduction}
\input{sections/02-related-work}
\input{sections/03-methods}
\input{sections/04-results}
\input{sections/05-discussion}
\input{sections/06-conclusion}

\bibliographystyle{IEEEtran}
\bibliography{references}

\end{document}

Multi-Author Collaboration

Sharing and Permissions

Role	Capabilities
Owner	Full control, can delete project, manage collaborators
Editor	Can edit all files, cannot manage collaborators
Viewer	Read-only access, can download but not modify

Share via:

• Link sharing: Generate a read-only or edit link (anyone with the link can access)
• Email invitation: Invite specific collaborators by email with role assignment

Author Coordination Best Practices

1. Assign sections: Each author owns specific .tex files to minimize merge conflicts.
2. Use comments: Overleaf supports inline comments (% TODO: revise this paragraph) and threaded review comments.
3. Use custom commands for notes:

% In preamble.tex, define author-specific annotation commands
\usepackage{xcolor}
\newcommand{\alice}[1]{\textcolor{blue}{[Alice: #1]}}
\newcommand{\bob}[1]{\textcolor{red}{[Bob: #1]}}
\newcommand{\todo}[1]{\textcolor{orange}{[TODO: #1]}}

% In text:
This result is surprising \alice{Should we add more analysis here?}
and warrants further investigation \todo{Add statistical test}.

4. Track changes: Overleaf Premium includes a track-changes mode. For free plans, use the changes package:

\usepackage{changes}
\definechangesauthor[name={Alice}, color=blue]{AL}
\definechangesauthor[name={Bob}, color=red]{BO}

% Usage:
\added[id=AL]{This is new text added by Alice.}
\deleted[id=BO]{This text was removed by Bob.}
\replaced[id=AL]{new text}{old text}

Git Integration

Overleaf + GitHub Sync

Overleaf Premium supports bidirectional GitHub sync:

1. In Overleaf, go to Menu > Sync > GitHub
2. Link your GitHub account and select or create a repository
3. Pull/push changes between Overleaf and GitHub

Overleaf + Local Git

# Clone your Overleaf project via git
git clone https://git.overleaf.com/YOUR_PROJECT_ID my-paper
cd my-paper

# Edit locally, then push back to Overleaf
git add -A
git commit -m "Updated results table"
git push origin master

# Pull changes made on Overleaf
git pull origin master

Credentials: Use your Overleaf email as username and an Overleaf-generated token as password.

Compilation and Debugging

Common Compilation Errors

Error	Cause	Fix
Undefined control sequence	Missing package or typo in command	Check \usepackage or spelling
Missing $ inserted	Math symbol outside math mode	Wrap in $...$ or \text{...}
File not found	Incorrect path in \input or \includegraphics	Check file names (case-sensitive on Overleaf)
Overfull \hbox	Content too wide for column	Resize figure, adjust text, or add \sloppy
Citation undefined	BibTeX entry missing or key mismatch	Verify .bib entry key matches \cite{}

Debugging Tips

• Use Recompile from scratch (Ctrl+Shift+Enter) to clear cache
• Check the Logs and output files panel for detailed error messages
• Use \listfiles in preamble to see which packages are loaded
• Overleaf uses TeX Live 2024; check package compatibility if using older templates

Submission Workflow

Preparing for Journal Submission

1. Flatten the project: Some journals require a single .tex file.

# Use latexpand to flatten \input commands
latexpand main.tex > submission.tex

2. Check formatting: Verify page limits, font sizes, margin requirements.
3. Download as zip: Menu > Download > Source to get all files.
4. Convert figures: Ensure all figures are in accepted formats (PDF, EPS, or high-res PNG/TIFF).
5. Clean up: Remove TODO comments, author annotation commands, and debug code.

% Add to preamble for submission: disable all annotation commands
\renewcommand{\alice}[1]{}
\renewcommand{\bob}[1]{}
\renewcommand{\todo}[1]{}
