Literature Review

Help write academic literature reviews using a multi-engine search integration (S2, OA, CR, PM).

Capabilities

• Multi-Source Search: Find relevant academic papers using Semantic Scholar (S2), OpenAlex (OA), Crossref (CR), and PubMed (PM).
• Full Abstracts: All sources now return complete abstracts (PubMed uses efetch for full XML records).
• DOI Extraction: DOIs are extracted from all sources for cross-referencing and deduplication.
• Automatic Deduplication: When searching multiple sources (--source all or --source both), results are automatically deduplicated by DOI.
• Polite Access: Automatic email identification for OpenAlex/Crossref "Polite Pool" (via USER_EMAIL env var).
• Abstract Reconstruction: Reconstructs abstracts from OpenAlex inverted index format.
• Synthesis: Group papers by theme and draft review sections based on metadata.
