Citation Management

Overview

Manage citations systematically throughout the research and writing process. This skill provides tools and strategies for searching academic databases (Google Scholar, PubMed), extracting accurate metadata from multiple sources (CrossRef, PubMed, arXiv), validating citation information, and generating properly formatted BibTeX entries.

Critical for maintaining citation accuracy, avoiding reference errors, and ensuring reproducible research. Integrates seamlessly with the literature-review skill for comprehensive research workflows.

When to Use This Skill

Use this skill when:

• Searching for specific papers on Google Scholar or PubMed
• Converting DOIs, PMIDs, or arXiv IDs to properly formatted BibTeX
• Extracting complete metadata for citations (authors, title, journal, year, etc.)
• Validating existing citations for accuracy
• Cleaning and formatting BibTeX files
• Finding highly cited papers in a specific field
• Verifying that citation information matches the actual publication
• Building a bibliography for a manuscript or thesis
• Checking for duplicate citations
• Ensuring consistent citation formatting

Visual Enhancement with Scientific Schematics

When creating documents with this skill, always consider adding scientific diagrams and schematics to enhance visual communication.

If your document does not already contain schematics or diagrams:

• Use the scientific-schematics skill to generate AI-powered publication-quality diagrams
• Simply describe your desired diagram in natural language
• Nano Banana Pro will automatically generate, review, and refine the schematic

For new documents: Scientific schematics should be generated by default to visually represent key concepts, workflows, architectures, or relationships described in the text.

How to generate schematics:

python scripts/generate_schematic.py "your diagram description" -o figures/output.png

The AI will automatically:

• Create publication-quality images with proper formatting
• Review and refine through multiple iterations
• Ensure accessibility (colorblind-friendly, high contrast)
• Save outputs in the figures/ directory

When to add schematics:

• Citation workflow diagrams
• Literature search methodology flowcharts
• Reference management system architectures
• Citation style decision trees
• Database integration diagrams
• Any complex concept that benefits from visualization

For detailed guidance on creating schematics, refer to the scientific-schematics skill documentation.

Core Workflow

Citation management follows a systematic process:

Phase 1: Paper Discovery and Search

Goal: Find relevant papers using academic search engines.

Google Scholar Search

Google Scholar provides the most comprehensive coverage across disciplines.

Basic Search:

# Search for papers on a topic
python scripts/search_google_scholar.py "CRISPR gene editing" \
  --limit 50 \
  --output results.json

# Search with year filter
python scripts/search_google_scholar.py "machine learning protein folding" \
  --year-start 2020 \
  --year-end 2024 \
  --limit 100 \
  --output ml_proteins.json

Advanced Search Strategies (see references/google_scholar_search.md):

• Use quotation marks for exact phrases: "deep learning"
• Search by author: author:LeCun
• Search in title: intitle:"neural networks"
• Exclude terms: machine learning -survey
• Find highly cited papers using sort options
• Filter by date ranges to get recent work

Best Practices:

• Use specific, targeted search terms
• Include key technical terms and acronyms
• Filter by recent years for fast-moving fields
• Check "Cited by" to find seminal papers
• Export top results for further analysis

PubMed Search

PubMed specializes in biomedical and life sciences literature (35+ million citations).

Basic Search:

# Search PubMed
python scripts/search_pubmed.py "Alzheimer's disease treatment" \
  --limit 100 \
  --output alzheimers.json

# Search with MeSH terms and filters
python scripts/search_pubmed.py \
  --query '"Alzheimer Disease"[MeSH] AND "Drug Therapy"[MeSH]' \
  --date-start 2020 \
  --date-end 2024 \
  --publication-types "Clinical Trial,Review" \
  --output alzheimers_trials.json

Advanced PubMed Queries (see references/pubmed_search.md):

• Use MeSH terms: "Diabetes Mellitus"[MeSH]
• Field tags: "cancer"[Title], "Smith J"[Author]
• Boolean operators: AND, OR, NOT
• Date filters: 2020:2024[Publication Date]
• Publication types: "Review"[Publication Type]
• Combine with E-utilities API for automation

Best Practices:

• Use MeSH Browser to find correct controlled vocabulary
• Construct complex queries in PubMed Advanced Search Builder first
• Include multiple synonyms with OR
• Retrieve PMIDs for easy metadata extraction
• Export to JSON or directly to BibTeX

Phase 2: Metadata Extraction

Goal: Convert paper identifiers (DOI, PMID, arXiv ID) to complete, accurate metadata.

Quick DOI to BibTeX Conversion

For single DOIs, use the quick conversion tool:

# Convert single DOI
python scripts/doi_to_bibtex.py 10.1038/s41586-021-03819-2

# Convert multiple DOIs from a file
python scripts/doi_to_bibtex.py --input dois.txt --output references.bib

# Different output formats
python scripts/doi_to_bibtex.py 10.1038/nature12345 --format json

Comprehensive Metadata Extraction

For DOIs, PMIDs, arXiv IDs, or URLs:

# Extract from DOI
python scripts/extract_metadata.py --doi 10.1038/s41586-021-03819-2

# Extract from PMID
python scripts/extract_metadata.py --pmid 34265844

# Extract from arXiv ID
python scripts/extract_metadata.py --arxiv 2103.14030

# Extract from URL
python scripts/extract_metadata.py --url "https://www.nature.com/articles/s41586-021-03819-2"

# Batch extraction from file (mixed identifiers)
python scripts/extract_metadata.py --input identifiers.txt --output citations.bib

Metadata Sources (see references/metadata_extraction.md):

1. CrossRef API: Primary source for DOIs

   • Comprehensive metadata for journal articles
   • Publisher-provided information
   • Includes authors, title, journal, volume, pages, dates
   • Free, no API key required

2. PubMed E-utilities: Biomedical literature

   • Official NCBI metadata

Literature Review Skill → Systematic search and synthesis Citation Management Skill → Technical citation handling

Combined Workflow:

1. Use literature-review for comprehensive multi-database search
2. Use citation-management to extract and validate all citations
3. Use literature-review to synthesize findings thematically
4. Use citation-management to verify final bibliography accuracy

# After completing literature review
# Verify all citations in the review document
python scripts/validate_citations.py my_review_references.bib --report review_validation.json

# Format for specific citation style if needed
python scripts/format_bibtex.py my_review_references.bib \
  --style nature \
  --output formatted_refs.bib

Search Strategies

Google Scholar Best Practices

Finding Seminal and High-Impact Papers (CRITICAL):

Always prioritize papers based on citation count, venue quality, and author reputation:

Citation Count Thresholds:

Paper Age	Citations	Classification
0-3 years	20+	Noteworthy
0-3 years	100+	Highly Influential
3-7 years	100+	Significant
3-7 years	500+	Landmark Paper
7+ years	500+	Seminal Work
7+ years	1000+	Foundational

Venue Quality Tiers:

• Tier 1 (Prefer): Nature, Science, Cell, NEJM, Lancet, JAMA, PNAS
• Tier 2 (High Priority): Impact Factor >10, top conferences (NeurIPS, ICML, ICLR)
• Tier 3 (Good): Specialized journals (IF 5-10)
• Tier 4 (Sparingly): Lower-impact peer-reviewed venues

Author Reputation Indicators:

• Senior researchers with h-index >40
• Multiple publications in Tier-1 venues
• Leadership at recognized institutions
• Awards and editorial positions

Search Strategies for High-Impact Papers:

• Sort by citation count (most cited first)
• Look for review articles from Tier-1 journals for overview
• Check "Cited by" for impact assessment and recent follow-up work
• Use citation alerts for tracking new citations to key papers
• Filter by top venues using source:Nature or source:Science
• Search for papers by known field leaders using author:LastName

Advanced Operators (full list in references/google_scholar_search.md):

"exact phrase"           # Exact phrase matching
author: "Krish Ujeniya"
intitle:keyword          # Search in title only
source:journal           # Search specific journal
-exclude                 # Exclude terms
OR                       # Alternative terms
2020..2024              # Year range

Example Searches:

# Find recent reviews on a topic
"CRISPR" intitle:review 2023..2024

# Find papers by specific author on topic
author: "Krish Ujeniya"

# Find highly cited foundational work
"deep learning" 2012..2015 sort:citations

# Exclude surveys and focus on methods
"protein folding" -survey -review intitle:method

PubMed Best Practices

Using MeSH Terms: MeSH (Medical Subject Headings) provides controlled vocabulary for precise searching.

1. Find MeSH terms at https://meshb.nlm.nih.gov/search
2. Use in queries: "Diabetes Mellitus, Type 2"[MeSH]
3. Combine with keywords for comprehensive coverage

Field Tags:

[Title]              # Search in title only
[Title/Abstract]     # Search in title or abstract
[Author]             # Search by author name
[Journal]            # Search specific journal
[Publication Date]   # Date range
[Publication Type]   # Article type
[MeSH]              # MeSH term

Building Complex Queries:

# Clinical trials on diabetes treatment published recently
"Diabetes Mellitus, Type 2"[MeSH] AND "Drug Therapy"[MeSH] 
AND "Clinical Trial"[Publication Type] AND 2020:2024[Publication Date]

# Reviews on CRISPR in specific journal
"CRISPR-Cas Systems"[MeSH] AND "Nature"[Journal] AND "Review"[Publication Type]

# Specific author's recent work
"Smith AB"[Author] AND cancer[Title/Abstract] AND 2022:2024[Publication Date]

Best Practices

Search Strategy

1. Start broad, then narrow:

   • Begin with general terms to understand the field
   • Refine with specific keywords and filters
   • Use synonyms and related terms

2. Use multiple sources:

   • Google Scholar for comprehensive coverage
   • PubMed for biomedical focus
   • arXiv for preprints
   • Combine results for completeness

3. Leverage citations:

   • Check "Cited by" for seminal papers
   • Review references from key papers
   • Use citation networks to discover related work

4. Document your searches:

   • Save search queries and dates
   • Record number of results
   • Note any filters or restrictions applied

Metadata Extraction

1. Always use DOIs when available:

   • Most reliable identifier
   • Permanent link to the publication
   • Best metadata source via CrossRef

2. Verify extracted metadata:

   • Check author names are correct
   • Verify journal/conference names
   • Confirm publication year
   • Validate page numbers and volume

3. Handle edge cases:

   • Preprints: Include repository and ID
   • Preprints later published: Use published version
   • Conference papers: Include conference name and location
   • Book chapters: Include book title and editors

4. Maintain consistency:

   • Use consistent author name format
   • Standardize journal abbreviations
   • Use same DOI format (URL preferred)

BibTeX Quality

1. Follow conventions:

   • Use meaningful citation keys (FirstAuthor2024keyword)
   • Protect capitalization in titles with {}
   • Use -- for page ranges (not single dash)
   • Include DOI field for all modern publications

2. Keep it clean:

   • Remove unnecessary fields
   • No redundant information
   • Consistent formatting
   • Validate syntax regularly

3. Organize systematically:

   • Sort by year or topic
   • Group related papers
   • Use separate files for different projects
   • Merge carefully to avoid duplicates

Validation

1. Validate early and often:

   • Check citations when adding them
   • Validate complete bibliography before submission
   • Re-validate after any manual edits

2. Fix issues promptly:

   • Broken DOIs: Find correct identifier
   • Missing fields: Extract from original source
   • Duplicates: Choose best version, remove others
   • Format errors: Use auto-fix when safe

3. Manual review for critical citations:

   • Verify key papers cited correctly
   • Check author names match publication
   • Confirm page numbers and volume
   • Ensure URLs are current

Common Pitfalls to Avoid

1. Single source bias: Only using Google Scholar or PubMed

   • Solution: Search multiple databases for comprehensive coverage

2. Accepting metadata blindly: Not verifying extracted information

   • Solution: Spot-check extracted metadata against original sources

3. Ignoring DOI errors: Broken or incorrect DOIs in bibliography

   • Solution: Run validation before final submission

4. Inconsistent formatting: Mixed citation key styles, formatting

   • Solution: Use format_bibtex.py to standardize

5. Duplicate entries: Same paper cited multiple times with different keys

   • Solution: Use duplicate detection in validation

6. Missing required fields: Incomplete BibTeX entries

   • Solution: Validate and ensure all required fields present

7. Outdated preprints: Citing preprint when published version exists

   • Solution: Check if preprints have been published, update to journal version

8. Special character issues: Broken LaTeX compilation due to characters

   • Solution: Use proper escaping or Unicode in BibTeX

9. No validation before submission: Submitting with citation errors

   • Solution: Always run validation as final check

10. Manual BibTeX entry: Typing entries by hand

    • Solution: Always extract from metadata sources using scripts
