OPDS catalogs
Read Flow can search external OPDS catalogs and pull titles directly into your library, without leaving the app.
Built-in catalogs
Two catalogs are enabled by default:
[[online_library.catalogs]]type = "builtin"id = "project_gutenberg"enabled = true
[[online_library.catalogs]]type = "builtin"id = "standard_ebooks"enabled = trueToggle either one off from Preferences → Online libraries, or by setting enabled = false
directly in read-flow.toml.
Searching
Open the Online library search from the web app’s search bar — results show cover, title, and author, with a one-click Add to library action that downloads and scans the file in.
