BibTeX File Merger

A Python script for merging multiple BibTeX .bib files, resolve conflicts, and removes duplicates.

Usage

python bib-merger.py [options] input1.bib [input2.bib input3.bib ...] output.bib

Arguments

• input1.bib, input2.bib, etc.: Input BibTeX files to merge/examine
• output.bib: Output file for merged entries
• --no-interactive: (Optional) Run in non-interactive mode, automatically choosing entries when conflicts occur
• --overwrite: (Optional) Overwrite the output file without asking for confirmation

Examples

# Interactive mode (default)
python bib-merger.py file1.bib file2.bib output.bib

# Non-interactive mode
python bib-merger.py --no-interactive file1.bib file2.bib output.bib

How It Works

1. Consistency checks:
   • Articles with the same title & type should have the same key
   • Articles with the same key should have the same title & type
   • Note: conference/ journal/ preprint article with the same title are considered different articles
2. In interactive mode, it prompts the user to resolve conflicts
3. In non-interactive mode, it automatically chooses entries based on their first appearance

• e) or automatic selection (non-interactive mode)

Known Issues

• If the title field contains comma (,), it might be truncated when parsing title. This parsed title field is only used for consistency checks. The final output is not affected.
