About this skill

Problem

Engineers often need more than “find a book.” They need to know whether a title has a legally readable ebook: public-domain download, library borrowing, preview, or purchase only. The hard part is inconsistent multi-source data. Open Library, Google Books, Project Gutenberg, Internet Archive, Douban, and WeChat Read return different fields. Overseas sources can be slow from mainland China, while titles, translations, and multiple editions can be easily mismatched. A flat list of links is neither reliable nor safe to deliver.

How It Works

The skill treats ebook lookup as a bounded search workflow. It starts with one of three entry points: title/author, ISBN, or keywords. It then normalizes the hits, assesses legality, and returns a structured result. Legal sources are ranked by public domain, borrowing, and preview/purchase, with cross-checks against Open Library and Google Books. Public-domain books are supplemented with direct EPUB links from Project Gutenberg or Internet Archive. For Chinese titles or unstable overseas access, it prefers Douban Books and WeChat Read, then falls back to WebSearch. Every result carries format, legality, and source confidence, so probable editions are not presented as confirmed assets.

Boundaries

It does not provide piracy or shadow-library access, and it does not fall back to gray sources when no legal full text exists. Copyrighted books are limited to preview, borrowing, or purchase. If the goal is feeding book-to-skill-adapter, prefer public-domain EPUB files or a legally owned copy. The skill is best for single-title lookup and source verification; batch searches require repeated calls and attention to Google Books rate limits.

Use Cases

  • Confirm whether a titled book has a borrowable or previewable ebook.
  • Use an ISBN to pin down the exact edition, year, and format availability.
  • Find a public-domain EPUB link before feeding a book to an adapter.
  • Check Douban or WeChat Read when overseas catalog APIs are unstable.

Best For

  • Skill-builder engineers who need legally usable ebook material for adapters.
  • Technical researchers who must distinguish public-domain, borrow, preview, and buy.
  • Library support staff checking domestic Chinese reading and purchase clues.
  • Compliance-aware editors who need each hit labeled with format and source trust.
