PyScholarly

An async Python library for scraping Google Scholar profiles using Playwright, with support for proxy rotation and detailed citation tracking.

⚠️ Disclaimer: This project is for academic and research purposes only. Please be mindful of Google Scholar's terms of service and rate limiting. Use responsibly and at your own risk.

Installation

pip install pyscholarly

Features

• Async/await support for efficient data fetching
• Proxy support with rotation strategies:
  • Sequential rotation
  • Random rotation
  • Support for authenticated proxies (username/password)
• Comprehensive citation metrics:
  • All-time citations
  • Recent citations (last 5 years)
  • Year-to-date citations per publication
  • H-index and i10-index (all-time and recent)
• Publication details:
  • Title, authors, venue, year
  • Citation counts (all-time and YTD)
• Debug logging and HTML page saving for troubleshooting
• Headless mode support
• Modern Playwright-based scraping

Usage

Basic Usage

from pyscholarly import fetch_scholar_data
import asyncio

async def main():
    # Fetch data for a Google Scholar profile
    author_id = "SCHOLAR_ID"  # Replace with actual Google Scholar ID
    data = await fetch_scholar_data(author_id)
    
    print(f"Author: {data['name']}")
    print(f"Total citations: {data['citedby']}")
    print(f"Recent citations: {data['citedby_recent']}")
    print(f"h-index: {data['hindex']}")
    
    # Print publications with YTD citations
    print("\nPublications:")
    for pub in data['publications']:
        print(f"- {pub['bib']['title']} ({pub['year']}):")
        print(f"  - Total citations: {pub['num_citations']}")
        print(f"  - YTD citations: {pub['ytd_citations']}")

if __name__ == "__main__":
    asyncio.run(main())

Advanced Usage with Proxies

import logging
from pyscholarly import fetch_scholar_data

# Setup logging
logging.basicConfig(level=logging.DEBUG)
logger = logging.getLogger(__name__)

async def main():
    # Single proxy
    proxy = "username:password@host:port"
    
    # Or multiple proxies
    proxies = [
        "username1:password1@host1:port1",
        "username2:password2@host2:port2"
    ]
    
    data = await fetch_scholar_data(
        scholar_id="SCHOLAR_ID",
        proxies=proxies,
        proxy_rotation="random",  # or "sequential"
        headless=True,
        logger=logger
    )
