Using PWL for Research

Finding Papers by Topic

bash
# Clone the repository
git clone https://github.com/papers-we-love/papers-we-love.git

# Browse categories
ls papers-we-love/

# Each directory has a README with curated descriptions
cat papers-we-love/distributed_systems/README.md

Programmatic Access

python
import os
import glob

PWL_PATH = "./papers-we-love"

# List all categories
categories = [d for d in os.listdir(PWL_PATH)
              if os.path.isdir(os.path.join(PWL_PATH, d))
              and not d.startswith('.')]
print(f"Categories: {len(categories)}")

# Find papers in a category
ml_papers = glob.glob(f"{PWL_PATH}/machine_learning/*.pdf")
for p in ml_papers:
    print(f"  {os.path.basename(p)}")

# Search across all READMEs for a topic
import re
for readme in glob.glob(f"{PWL_PATH}/*/README.md"):
    with open(readme) as f:
        content = f.read()
    if re.search(r"consensus|paxos|raft", content, re.I):
        category = os.path.basename(os.path.dirname(readme))
        print(f"Found in: {category}")

Reading Group Integration
