ChatGPT plugin

Search Japanese libraries

View in ChatGPT directory

CALIL for AI lets ChatGPT search the catalogs of more than 7,400 public, university, and specialized libraries in Japan.

What you can do:

  • Find library systems by library name or region (for example, a city or ward) and get the system IDs used for catalog search.
  • Search up to 15 library systems at once by keyword, title, author, publisher, ISBN, or NDC classification, with optional publication-year filters. Results list matching books, which systems hold them, and a link to each library's catalog page.
  • Browse the Nippon Decimal Classification (NDC 9th edition), including broader, narrower, and related classes.

Intended users: readers, students, researchers, and librarians looking for books held by libraries in Japan.

Limitations: Catalog data is provided in Japanese. Search results show which libraries hold a book and link to their catalog pages; loan status and reservations are handled on each library's own site. The plugin cannot borrow, reserve, or purchase books, and it does not access library user accounts. A CALIL account connection is required. Searches are subject to rate limits that control the volume of requests within a given time period.
