# Nanjing University Library Catalog (OPAC)

**Canonical:** https://apis.io/apis/nanjing/opac/  
**Provider:** Nanjing University — https://apis.io/providers/nanjing/  
**Base URL:** https://opac.nju.edu.cn/  
**Documentation:** https://lib.nju.edu.cn/

Nanjing University Library Catalog (OPAC) is one of 14 APIs that [Nanjing University](https://apis.io/providers/nanjing/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Library, Catalog, and Discovery.

The library's catalog host. It is live but restricted to the campus network: every route, including an OAI-PMH probe, returns HTTP 403 with the body "请使用南大VPN访问!" ("please access via the NJU VPN"). Recorded as gated rather than absent — this is a finding about network policy, not evidence that the catalog does not exist.
