Download books from an OPDS catalog using a Calibre plugin.

Calibre is a cross-platform open-source suite of e-book software. Calibre supports organizing existing e-books into virtual libraries, displaying, editing, creating and converting e-books, as well as syncing e-books with a variety of e-readers.

The Open Publication Distribution System (OPDS) catalog format is a syndication format for electronic publications based on Atom and HTTP. OPDS catalogs enable the aggregation, distribution, discovery, and acquisition of electronic publications.

The Calibre OPDS Client is a Calibre plugin that reads from an OPDS server and downloads the contents to a Calibre library.

2. Install the plugin.

   cd calibre_plugin
   calibre-customize -b .

3. Restart Calibre.

   1. Open the Preferences menu.
   2. Under the Interface section, click on the button labeled Toolbars & menus.

   4. Select OPDS Client under Available actions on the left side.
   5. Click the right arrow (>) to add it to the main toolbar.
   6. Click Apply, then Close the Preferences menu.

         • The updated timestamps may not show up immediately, but they will show up after the first update of the display, and the books will be ordered according to the timestamp after stopping and starting calibre
