EPUB

Both EPUB2 and EPUB3 formats are viable on Manifold. For best results, make sure your EPUB file validates with no errors before loading it to the system.

Note. There are no file size limitations for EPUB uploads.

If you are creating your EPUB file from a program like InDesign, avoid exporting it as a fixed-layout document (FXL): fixed-layout EPUBs are structured very specifically to mimic the look of a printed work, and the format of the underlying coding will prevent your file from ingesting correctly into Manifold.

The table of contents represented in the toc.ncx or toc.xhtml files (for EPUB versions 2 or 3, respectively) will be mirrored in the Manifold reader’s Contents dropdown.

The title bar in the Manifold reader secures the title of the text from the dc:title element in EPUB’s content.opf file. The title of individual sections, which also display in the title bar are first looked for in the toc.ncx or toc.xhtml files. If the system cannot find one there for a section, it will then look to the individual XHTML files, beginning by searching for a top-level header, or, failing that, the <title> element.

For more about the EPUB spec, please refer to the standard as defined on the IDPF website. Suggestions included in the HTML section of this documentation will also generally work when modifying EPUBs.

Note. It is not possible to include an EPUB document as part of a Manifest upload.
