Comprehensive Citation Management

A scientific computing skill for managing citations throughout the research and writing process. Comprehensive Citation Management helps you organize references, format bibliographies in multiple citation styles, integrate with reference databases, and maintain consistent citations across manuscripts and documents.

When to Use This Skill

Choose Comprehensive Citation Management when:

• Organizing references for a research paper or thesis
• Converting between citation formats (APA, MLA, Chicago, Vancouver)
• Building BibTeX databases from DOIs or PubMed IDs
• Managing large reference collections with tagging and categorization

Consider alternatives when:

• You need a GUI reference manager (use Zotero, Mendeley, or EndNote)
• You need full-text PDF management (use a dedicated reference manager)
• You're writing a blog post without formal citations

Quick Start

Copy
claude "Create a BibTeX entry from this DOI: 10.1038/s41586-021-03819-2"

Copy
import requests

doi = "10.1038/s41586-021-03819-2"
headers = {"Accept": "application/x-bibtex"}
response = requests.get(f"https://doi.org/{doi}", headers=headers)

print(response.text)
# @article{Jumper_2021,
#   title={Highly accurate protein structure prediction with AlphaFold},
#   author={Jumper, John and Evans, Richard and ...},
#   journal={Nature},
#   volume={596},
#   pages={583--589},
#   year={2021},
#   doi={10.1038/s41586-021-03819-2}
# }

BibTeX Management

Copy
import bibtexparser

# Parse existing .bib file
with open("references.bib", "r") as f:
    bib_db = bibtexparser.load(f)

print(f"References: {len(bib_db.entries)}")

# Add new entry
new_entry = {
    "ENTRYTYPE": "article",
    "ID": "jumper2021alphafold",
    "title": "Highly accurate protein structure prediction with AlphaFold",
    "author": "Jumper, John and Evans, Richard",
    "journal": "Nature",
    "volume": "596",
    "pages": "583--589",
    "year": "2021",
    "doi": "10.1038/s41586-021-03819-2"
}
bib_db.entries.append(new_entry)

# Write updated .bib file
with open("references.bib", "w") as f:
    bibtexparser.dump(bib_db, f)

DOI-Based Reference Building

Copy
def doi_to_bibtex(doi):
    """Convert a DOI to BibTeX entry"""
    headers = {"Accept": "application/x-bibtex"}
    resp = requests.get(f"https://doi.org/{doi}", headers=headers,
                       allow_redirects=True)
    if resp.status_code == 200:
        return resp.text
    return None

def pubmed_to_bibtex(pmid):
    """Convert PubMed ID to BibTeX via NCBI"""
    from Bio import Entrez
    Entrez.email = "[email protected]"
    handle = Entrez.efetch(db="pubmed", id=pmid, rettype="xml")
    records = Entrez.read(handle)
    article = records["PubmedArticle"][0]["MedlineCitation"]["Article"]
    return format_as_bibtex(article)

# Batch convert DOIs
dois = [
    "10.1038/s41586-021-03819-2",
    "10.1126/science.abj8754",
    "10.1038/s41592-021-01252-x"
]
for doi in dois:
    bib = doi_to_bibtex(doi)
    print(bib)

Configuration

Parameter	Description	Default
citation_style	Output citation format	apa
bib_file	Path to .bib database	references.bib
auto_fetch_metadata	Resolve DOIs automatically	true
dedup_strategy	Deduplication method (DOI, title)	doi
sort_order	Bibliography sort order	author_year

Best Practices

1. Use DOIs as the primary identifier. DOIs are permanent, unique identifiers for publications. Always include the DOI in your BibTeX entries — it enables automatic metadata lookup, deduplication, and linking to the full text.

2. Maintain a single centralized .bib file. Keep all references in one BibTeX file per project and let your LaTeX or Markdown build system handle formatting. This prevents duplicate entries and makes bibliography management tractable.

3. Validate BibTeX entries before submission. Check for missing required fields (year, author, title), broken DOIs, and encoding issues (LaTeX special characters). Tools like bibtex-tidy can normalize and validate your .bib file.

4. Tag references for organization. Use the keywords field in BibTeX entries to categorize references by topic, methodology, or relevance. This makes it easy to generate topic-specific bibliographies from a large reference collection.

5. Convert citation styles programmatically. Use CSL (Citation Style Language) with tools like citeproc-py or Pandoc for reliable style conversion. Manual reformatting introduces errors, especially with author name formats and date styles.

Common Issues

BibTeX keys conflict across merged .bib files. Use a consistent key generation scheme: firstauthor_year_keyword (e.g., jumper2021alphafold). When merging files, check for key duplicates and rename before merging.

Special characters break LaTeX compilation. BibTeX requires LaTeX escaping for characters like &, %, #, and accented letters (ü → "{u}). Use UTF-8 encoded .bib files with \usepackage[utf8]{inputenc} in LaTeX, or escape characters in the .bib entries.

Citation formatting doesn't match target journal requirements. Each journal has specific citation style requirements. Download the journal's CSL file from the Zotero Style Repository and use it with Pandoc or your citation processor. Don't manually format citations — it's error-prone and tedious.
