Book Metasearch

Book note maker with metasearch across Aladin · Kakao · Google Books · Open Library, queried in parallel. Korean-first with foreign fallback.

Successor to anpigon/obsidian-book-search-plugin (unmaintained). Built to solve the Naver Book Search API EOL (2026-08-01) and provide a proper Korean-first book note workflow.

Install

From the community plugin directory:

1. In Obsidian, open Settings → Community plugins
2. Turn off Restricted mode if enabled
3. Click Browse and search for Book Metasearch
4. Click Install, then Enable

Features

Core (v1.0)

• 4-provider metasearch: Aladin (Korean primary) · Kakao (Korean recall) · Google Books (foreign primary) · Open Library (foreign covers/ISBN)
• Two strategies: Sequential fallback (default) or parallel Fanout with ISBN13 dedupe
• Commands: Search books · Search by ISBN · Search based on current note · Update book info · Migration helper
• Template file support with {{variable}} substitution — Templater <% %> blocks are preserved for post-creation execution
• Frontmatter customization: useDefaultFrontmatter toggle · key case (as-is / camelCase / snake_case / kebab-case) · additional YAML fragment with {{variable}} substitution
• Cover image download to a configurable folder
• 37 ISO 639-1 locale codes for cross-provider language filtering
• API keys masked in settings with click-to-reveal
• Cover thumbnails in search results (opt-in)
• Naver EOL migration: opt-in helper detects an existing obsidian-book-search-plugin config and guides users through Aladin setup

v1.1 additions

• Auto-filled Abstract / Description section — new notes get the provider's book description written into the ## Abstract / Description block (HTML stripped). "Update book info in current note" refreshes it while preserving edits outside the auto-block markers.
• ISBN13 vault-wide duplicate detection — before creating a note, the plugin scans the vault. On match, DuplicateModal offers: open existing / update existing / create anyway / cancel. Backed by an incremental VaultBookIndex.
• Reading Log — three commands ("Mark book as wishlist / reading / read") with automatic startedAt / finishedAt date stamping (idempotent). New notes get a configurable initial status (default: wishlist).
• Insert book citation at cursor — editor command that emits a wikilink to an existing vault note (if any) or an unresolved link. Two link styles.
• Aladin used-book price check (opt-in) — surfaces used-book minimum prices as a Notice or appended ## Price Watch section.
• Redacted error diagnostics — healthcheck / migration failures auto-write a diagnostics note with secrets masked, so users can attach it to bug reports.

See CHANGELOG.md for the full v1.1.0 changelog.

Provider setup

Only Aladin and Kakao require API keys (both free, instant issuance). Google Books works without a key at a lower rate limit. Open Library needs no auth.

After installing, open Settings → Book Metasearch → Providers, paste keys, and hit Healthcheck on each provider.

Attribution

• Aladin: Book DB by Aladin (aladin.co.kr)

The Aladin OpenAPI general-tier terms don't strictly mandate a credit link, but keeping the "Book DB by Aladin" footer in generated notes is the polite (and forward-compatible if you ever upgrade to the premium tier). Leave the credit toggle on unless you have a specific reason.
