bioRxiv Database

Overview

This skill provides efficient Python-based tools for searching and retrieving preprints from the bioRxiv database. It enables comprehensive searches by keywords, authors, date ranges, and categories, returning structured JSON metadata that includes titles, abstracts, DOIs, and citation information. The skill also supports PDF downloads for full-text analysis.

When to Use This Skill

Use this skill when:

• Searching for recent preprints in specific research areas
• Tracking publications by particular authors
• Conducting systematic literature reviews
• Analyzing research trends over time periods
• Retrieving metadata for citation management
• Downloading preprint PDFs for analysis
• Filtering papers by bioRxiv subject categories

Core Search Capabilities

1. Keyword Search

Search for preprints containing specific keywords in titles, abstracts, or author lists.

Basic Usage:

python scripts/biorxiv_search.py \
  --keywords "CRISPR" "gene editing" \
  --start-date 2024-01-01 \
  --end-date 2024-12-31 \
  --output results.json

With Category Filter:

python scripts/biorxiv_search.py \
  --keywords "neural networks" "deep learning" \
  --days-back 180 \
  --category neuroscience \
  --output recent_neuroscience.json

Search Fields: By default, keywords are searched in both title and abstract. Customize with --search-fields:

python scripts/biorxiv_search.py \
  --keywords "AlphaFold" \
  --search-fields title \
  --days-back 365

2. Author Search

Find all papers by a specific author within a date range.

Basic Usage:

python scripts/biorxiv_search.py \
  --author "Smith" \
  --start-date 2023-01-01 \
  --end-date 2024-12-31 \
  --output smith_papers.json

Recent Publications:

# Last year by default if no dates specified
python scripts/biorxiv_search.py \
  --author "Johnson" \
  --output johnson_recent.json

3. Date Range Search

Retrieve all preprints posted within a specific date range.

Basic Usage:

python scripts/biorxiv_search.py \
  --start-date 2024-01-01 \
  --end-date 2024-01-31 \
  --output january_2024.json

With Category Filter:

python scripts/biorxiv_search.py \
  --start-date 2024-06-01 \
  --end-date 2024-06-30 \
  --category genomics \
  --output genomics_june.json

Days Back Shortcut:

# Last 30 days
python scripts/biorxiv_search.py \
  --days-back 30 \
  --output last_month.json

4. Paper Details by DOI

Retrieve detailed metadata for a specific preprint.

Basic Usage:

python scripts/biorxiv_search.py \
  --doi "10.1101/2024.01.15.123456" \
  --output paper_details.json

Full DOI URLs Accepted:

python scripts/biorxiv_search.py \
  --doi "https://doi.org/10.1101/2024.01.15.123456"

5. PDF Downloads

Download the full-text PDF of any preprint.

Basic Usage:

python scripts/biorxiv_search.py \
  --doi "10.1101/2024.01.15.123456" \
  --download-pdf paper.pdf

Batch Processing: For multiple PDFs, extract DOIs from a search result JSON and download each paper:

import json
from biorxiv_search import BioRxivSearcher

# Load search results
with open('results.json') as f:
    data = json.load(f)

searcher = BioRxivSearcher(verbose=True)

# Download each paper
for i, paper in enumerate(data['results'][:10]):  # First 10 papers
    doi = paper['doi']
    searcher.download_pdf(doi, f"papers/paper_{i+1}.pdf")

Common Usage Patterns

Literature Review Workflow

1. Broad keyword search:

python scripts/biorxiv_search.py \
  --keywords "organoids" "tissue engineering" \
  --start-date 2023-01-01 \
  --end-date 2024-12-31 \
  --category bioengineering \
  --output organoid_papers.json

1. Extract and review results:

import json

with open('organoid_papers.json') as f:
    data = json.load(f)

print(f"Found {data['result_count']} papers")

for paper in data['results'][:5]:
    print(f"\nTitle: {paper['title']}")
    print(f"Authors: {paper['authors']}")
    print(f"Date: {paper['date']}")
    print(f"DOI: {paper['doi']}")

1. Download selected papers:

from biorxiv_search import BioRxivSearcher

searcher = BioRxivSearcher()
selected_dois = ["10.1101/2024.01.15.123456", "10.1101/2024.02.20.789012"]

for doi in selected_dois:
    filename = doi.replace("/", "_").replace(".", "_") + ".pdf"
    searcher.download_pdf(doi, f"papers/{filename}")

Trend Analysis

Track research trends by analyzing publication frequencies over time:

python scripts/biorxiv_search.py \
  --keywords "machine learning" \
  --start-date 2020-01-01 \
  --end-date 2024-12-31 \
  --category bioinformatics \
  --output ml_trends.json

Then analyze the temporal distribution in the results.

Author Tracking

Monitor specific researchers' preprints:

# Track multiple authors
authors = ["Smith", "Johnson", "Williams"]

for author in authors:
    python scripts/biorxiv_search.py \
      --author "{author}" \
      --days-back 365 \
      --output "{author}_papers.json"

Python API Usage

For more complex workflows, import and use the BioRxivSearcher class directly:

from scripts.biorxiv_search import BioRxivSearcher

# Initialize
searcher = BioRxivSearcher(verbose=True)

# Multiple search operations
keywords_papers = searcher.search_by_keywords(
    keywords=["CRISPR", "gene editing"],
    start_date="2024-01-01",
    end_date="2024-12-31",
    category="genomics"
)

author_papers = searcher.search_by_author(
    author_name="Smith",
    start_date="2023-01-01",
    end_date="2024-12-31"
)

# Get specific paper details
paper = searcher.get_paper_details("10.1101/2024.01.15.123456")

# Download PDF
success = searcher.download_pdf(
    doi="10.1101/2024.01.15.123456",
    output_path="paper.pdf"
)

# Format results consistently
formatted = searcher.format_result(paper, include_abstract=True)

Best Practices

1. Use appropriate date ranges: Smaller date ranges return faster. For keyword searches over long periods, consider splitting into multiple queries.

1. Filter by category: When possible, use --category to reduce data transfer and improve search precision.

1. Respect rate limits: The script includes automatic delays (0.5s between requests). For large-scale data collection, add addi
