  • Overview
  • Scorecard
  • Updates2

An Obsidian plugin that fetches book metadata from ISBN and helps you manage your personal bookshelf as notes.

Features

  • Fetch book metadata by ISBN from NDL (National Diet Library of Japan), Google Books, and Open Library
  • Automatic cover image download with WebP conversion and local caching
  • Bookshelf views via Bases (Want to read / Reading / Finished)
  • Manual entry and editing of book notes
  • Manual cover image (drag & drop, clipboard paste, or file picker)
  • Bulk ISBN extraction from back-cover images to CSV
  • OCR fallback for printed ISBN-10 and ISBN-13 text when a barcode cannot be read (macOS)
  • Bulk bookshelf creation from an ISBN CSV file
  • High-resolution cover refresh with low-resolution rejection and provider fallback

From back-cover photos to an Obsidian bookshelf

  1. Take photos of the back covers of your books with an iPhone or camera.
  2. Select the photo directory from the barcode-scan icon in the Obsidian sidebar.
  3. The plugin detects ISBN barcodes, with OCR fallback for printed ISBN text, and exports a CSV file.
  4. Select that CSV from the library icon to fetch metadata and build the bookshelf.

Installation

From the Obsidian Community Plugins (planned)

Search for ISBN Bulk Import Bookshelf Builder in Settings → Community plugins and install.

Manual installation

Download the latest main.js, manifest.json, and styles.css from the Releases page and place them in:

<Vault>/.obsidian/plugins/isbn-bulk-import-bookshelf-builder/
├── main.js
├── manifest.json
└── styles.css

Then enable ISBN Bulk Import Bookshelf Builder in Settings → Community plugins.

Via BRAT

Add this repository through the BRAT plugin.

Usage

  1. Click the barcode-scan ribbon icon to scan ISBN barcodes from a directory of JPG, PNG, WebP, GIF, BMP, HEIC, or HEIF images.
  2. Click the library ribbon icon to fetch metadata and create book notes in bulk. The importer accepts an isbn column, or ISBNs in the first column of a headerless CSV.
  3. Use the book-marked ribbon icon to edit an existing book note.
  4. Replace a cover via "Set cover image manually" in the command palette.
  5. Run "Refresh metadata and descriptions for all books" to update existing notes in bulk while preserving reading status, progress, ratings, and notes.
  6. "Add descriptions to Kindle Highlights notes" requires the Kindle Highlights community plugin to be installed. Select its synced notes folder in this plugin's settings before running the command. It processes up to 150 unprocessed notes per run and skips notes already checked.
  7. Use "Refresh descriptions for all Kindle Highlights notes" only when every Kindle description needs to be queried again, since it can issue many API requests.

Requirements

  • Desktop only (uses Electron file dialog and local filesystem for cover caching).
  • Plugin loading has been verified on macOS 14.4.1 (Build 23E224).
  • The Kindle description command requires the Kindle Highlights community plugin and notes containing its Kindle tag, kindle-title, and kindle-author properties.
  • Primarily intended for books published in Japan, especially ISBNs beginning with 978-4. Overseas books may work when metadata is available from Google Books or Open Library, but they are not currently guaranteed or fully tested.

Network use

This plugin makes HTTPS requests to the following public services to fetch book metadata and cover images. ISBN lookups send the ISBN you enter. The Kindle description command sends the synced book title and author to Google Books.

  • NDL (National Diet Library of Japan) — https://ndlsearch.ndl.go.jp — primary metadata source for Japanese books.
  • Google Books API — https://www.googleapis.com/books/v1 — fallback metadata source.
  • Open Library — https://openlibrary.org and https://covers.openlibrary.org — final fallback for metadata and cover images.
  • openBD — https://api.openbd.jp — supplemental Japanese book metadata and descriptions.
  • Books.or.jp — https://thumbnail-s.images.books.or.jp and https://www.books.or.jp — fallback cover images for Japanese books.

All requests are issued through Obsidian's requestUrl API and are only triggered by explicit user actions, including ISBN lookup, bulk import, metadata refresh, and Kindle description commands. No background or telemetry traffic is generated.

File system access

On desktop, the "Set cover image manually" command opens an Electron file picker so you can choose an image from anywhere on your local disk. The selected file is read once via Node fs, converted to WebP, and saved into your vault's configured covers folder. The plugin does not retain any path outside your vault.

Vault access

The plugin enumerates Markdown files in the vault (vault.getMarkdownFiles()) for two reasons:

  1. Duplicate detection — when you add a book by ISBN, the plugin scans existing notes for the same isbn value in frontmatter to avoid creating duplicates.
  2. Book picker — the "Select and edit book note" command lists existing book notes filtered by the kind: book frontmatter.

The plugin does not read note bodies; only frontmatter is inspected. No file content is sent over the network.
