Aldiko Next supports open standards such as EPUB, PDF, and audiobooks via Readium Mobile, ensuring broad format compatibility. It also enables access to OPDS catalogs, including those generated by Calibre, which enhances library organization and discovery.

A casual reader could sync their personal EPUB library with a Calibre-generated catalog and borrow new releases from their local public library without switching apps.
