BibTeX DOI Finder

This Python script automatically searches for and appends Digital Object Identifiers (DOIs) to entries in a BibTeX file that lack them. It utilizes the CrossRef API to query DOIs based on article titles, enhancing the completeness of bibliographic references.

Features

• Parses BibTeX files to identify entries without DOIs.
• Queries the CrossRef API using titles of entries to find corresponding DOIs.
• Appends found DOIs to the BibTeX entries.
• Saves the updated BibTeX file with DOIs included.

Prerequisites

Before running this script, ensure you have the following installed:

• Python 3.x
• requests library
• pybtex library

Installation

1. Clone the Repository

   git clone https://github.com/yourusername/bibtex-doi-finder.git
   cd bibtex-doi-finder

2. Install Required Python Libraries

   Run the following command to install the necessary Python libraries:

   pip install requests pybtex

Usage

1. Prepare Your BibTeX File

   Ensure your BibTeX file is ready and located in an accessible directory.

2. Edit the Script

   Open doi_finder.py in a text editor and replace 'your_bibtex_file.bib' with the path to your BibTeX file.

3. Run the Script

   Execute the script from the command line:

   python doi_finder.py

   The script will process each entry in your BibTeX file, search for missing DOIs, and print the results. If a DOI is found, it will be appended to the entry. The script saves an updated version of your BibTeX file named updated_lib.bib.
