Connect GemReader to your home Calibre server, Kavita library, or university repository. Download books from your private cloud anytime.
Why Connect Custom OPDS Feeds?
Many dedicated readers host their personal ebook archives on home media servers or networked storage systems using Calibre Content Server, Kavita, or Komga. Re-downloading books through web browsers or transferring files via chat apps creates unnecessary friction.
By adding a custom OPDS feed into GemReader, you connect your personal home archive directly to your mobile bookshelf. You can browse your private categories, filter by tags, and download titles on demand whenever your device is connected to your home network.
What You'll Need
Before adding a custom catalog, make sure you have:
• **Catalog Address**: A valid, accessible HTTPS OPDS feed URL from your home server or institutional repository (e.g., https://my-server.example.com/opds). • **Credentials**: Your username and password if your home server enforces authentication. • **Network**: Active network access to reach your server host.
Step-by-Step Instructions
1. Open GemReader, tap the **+** button in the **Library** header, and select **Browse Free Books**. 2. Tap the **+ Add Catalog** button in the top right corner of the catalog browser. 3. Type a clear, recognizable name for your feed (for example, *Home Calibre Vault* or *Research Repository*). 4. Enter your server's secure `https://` feed address. 5. If your server is protected by a login, toggle **Requires Authentication** and enter your server username and password. 6. Tap **Save Catalog**. GemReader will test the connection and display your new shelf alongside the default public catalogs. 7. Tap your new catalog to browse your private authors, tags, and bookshelves, and tap **Download** on any title to save it locally.
Helpful Tips & Common Questions (Librarian's Advice)
• **Strict HTTPS Security**: To protect your server credentials and book downloads from eavesdropping on open networks, GemReader requires secure `https://` feed connections. • **Local Network Access**: If your Calibre server is configured to run only on your local home network (LAN), ensure your phone is connected to your home Wi-Fi when browsing and downloading. • **Permanent Local Retention**: When you download a book from your custom OPDS catalog, the file is saved permanently inside GemReader's private storage. You can continue reading even when away from your home server.
