How to Add a Custom OPDS Catalog Book Source
- Go to the Custom Download View.
- Tap “+” and select “Add Catalog”.
- Enter, say, “Project Gutenberg” as “Book Source Name”,
“m.gutenberg.org” as “Catalog Address” (required),
and “www.gutenberg.org/favicon.ico” as “Icon Address” (optional).
- Confirm that “Project Gutenberg” is indeed in the “Books from Catalogs (manual)” section.
