How to properly use English left and right double quotes in LaTeX?

Question

How to properly use English left and right double quotes in LaTeX? In LaTeX, correctly using English left and right double quotes can sometimes confuse users. The common issue arises when trying to insert proper opening (``) and closing ('') double quotes. A frequent mistake is using straight quotation marks (" ") directly from the keyboard, which results in uniform quotes that don't distinguish between opening and closing punctuation. To achieve professional typesetting, use two backticks (``) for the left double quote and two single quotes ('') for the right double quote. For example, ``LaTeX is powerful'' will render as proper opening and closing quotes. Additionally, ensure your document class and any loaded packages (like csquotes or babel) are configured correctly for English language settings. Misconfigured settings might still display incorrect symbols or encoding issues. Always compile a small test document to verify how quotes appear before finalizing larger projects. This attention to detail enhances readability and adheres to typographic standards.

1. Understanding the Basics of Quotes in LaTeX

In LaTeX, using English double quotes properly is crucial for maintaining typographic standards and enhancing readability. The first step is understanding the difference between straight quotation marks (" ") and curved quotes (``LaTeX is powerful''). Straight quotation marks are typically used in plain text but do not distinguish between opening and closing punctuation, which can lead to a less professional appearance.

• For left double quotes, use two backticks: ``.
• For right double quotes, use two single quotes: ''.

Example:

``This is a proper quote in LaTeX.''

2. Common Mistakes and Troubleshooting

A frequent mistake users make is directly typing straight quotation marks from their keyboard. This results in uniform quotes that lack distinction between opening and closing punctuation. To troubleshoot this issue, ensure your LaTeX editor or IDE does not automatically replace these characters with straight quotes.

Additionally, verify your document's language settings. Misconfigured packages such as \usepackage[english]{babel} or \usepackage{csquotes} might cause incorrect symbols or encoding issues. Below is an example configuration:

\documentclass{article}
\usepackage[english]{babel}
\usepackage{csquotes}

\begin{document}
``This is a test.''
\end{document}

3. Advanced Techniques for Professional Typesetting

To achieve even more professional typesetting, consider using the csquotes package. This package provides advanced tools for handling quotations in multiple languages and formats. For instance, it allows you to use commands like \enquote{}, which automatically handles the correct placement of quotation marks based on the document's language settings.

Command	Output
\enquote{LaTeX is powerful}	``LaTeX is powerful''
\enquote*{This is emphasized.}	``This is emphasized''

4. Testing and Validation Process

Always compile a small test document before finalizing larger projects. This ensures that all configurations, including those related to quotes, are functioning correctly. Below is a flowchart illustrating the testing process:

graph TD;
            A[Start] --> B[Create Test Document];
            B --> C[Insert Quotes];
            C --> D[Compile Document];
            D --> E[Verify Output];
            E --> F[Adjust Configurations if Needed];

This methodical approach helps identify potential issues early, saving time and effort in the long run.
