Similarly, Kobo won’t be accepting deliveries from Dec.19-29, and Barnes and Noble will be closed from Dec. 23-26 and Dec. 29-Jan.2.

However, Amazon and Google’s systems won’t be shut down during the holidays.

Reminder About EPUB Validation

Publishers that are providing distribution-ready files should make sure the ePubs validate and are free of errors before sending them to NBN. The latest ePub standard is 4.0.1, but some vendors are still using 3.0.1 to validate files and will reject files that don’t validate to that version. To check ePubs that are less than 10MB, you can use this IDPF validator. Common validation warnings and errors are below:

WARNING: Filenames contains spaces. Consider changing filenames such that URI escaping is not necessary
SOLUTION: Remove the spaces from the files names of the .html and .jpg files inside the ePub.
EPUBCHECK VERSION: 3.0.0, 3.0.1, 4.0.1

ERROR: element “font” not allowed anywhere; expected the element end-tag, text or element “a”, “abbr”, “acronym”, “applet”, “b”, “bdo”, “big”, “br”, “cite”, “code”, “del”, “dfn”, “em”, “i”, “iframe”, “img”, “ins”, “kbd”, “map”, “noscript”, “ns:svg”, “object”, “q”, “samp”, “script”, “small”, “span”, “strong”, “sub”, “sup”, “tt” or “var” (with xmlns:ns=”http://www.w3.org/2000/svg“)
SOLUTION: Instead of using a font tag, set the font size in the CSS stylesheet using the font-size property, and then apply that style to the line or paragraph that had the font tag.
EPUBCHECK VERSION: 3.0.0, 3.0.1, 4.0.1

ERROR: Non-standard stylesheet resource ‘OEBPS/page-template.xpgt’ of type ‘application/adobe-page-template+xml’. A fallback must be specified.
SOLUTION: Remove the reference to the page-template stylesheet.
EPUBCHECK VERSION: 3.0.1; This error is due to a glitch in epubcheck 3.0.1 but some vendors are still using that version, so files with this error won’t go up on those sites.

ERROR: OEBPS/Fonts/Fontname: referenced resource missing in the package (or /OEBPS/template.css: Referenced resource could not be found in the EPUB.)
SOLUTION: The font file is missing from within the ePub, In most cases, you can simply remove the src=”…” text from the place of reference since the ePub isn’t loading the font anyway.
EPUBCHECK VERSION: 3.0.0, 3.0.1, 4.0.1

ERROR: Referenced resource could not be found in the EPUB.
SOLUTION: A link or reference is made to content not provided within the ePub. This can be caused by several things including: 1. an improperly embedded font, 2. missing image file, or 3. incorrectly written hyperlink to a web address. Add the missing content or remove the reference.
EPUBCHECK VERSION: 3.0.0, 3.0.1, 4.0.1

ERROR: File name contains the following non-ascii characters: […]. Consider changing the filename.
SOLUTION: Change the file name of the image or html file that so that it contains only US keyboard characters.
EPUBCHECK VERSION: 3.0.0, 3.0.1, 4.0.1

Holiday Blackout Dates

It’s that time of year again—the time for vacations and gift buying. Around the holidays, some eBook vendors go on break, during which time no new content will be processed. The holiday blackout dates (for the vendors that have provided them) are:

Amazon: Dec.23-28
Apple: Dec.22-29
Barnes & Noble: Dec.25 & Jan.1
Kobo: Dec.22-29

There will be no distributions to these sites during these dates. To ensure that new content is live in time for the holidays, distribution-ready eBook files and metadata should be sent to your Digital Publishing Representative no later than Monday, December 14.

EPUB Validations

To make sure that files are accepted by all vendors we distribute to, ePubs need to validate to EpubCheck v. 3.0.1, which some vendors still use to validate files.

There are errors that appear when validating to 3.0.1 that don’t appear when validating to 3.0 or 4.0.1. For example, a common problem that prevents validation is the stylesheet being a template formatted for Adobe Digital Editions (ADE). Since the major sites and devices do not run Digital Editions, it is not necessary to format the ePub specifically for display in that program. If you are unable to provide files that validate, we work with a vendor that can convert your files for you.

Amazon:  Dec 19 – Dec 28
Apple:  Dec 22 – Dec 29
Kobo:  Dec 22 – Jan 2

During this time distributions to these sites will be suspended.  To ensure all new titles and promotional pricing scheduled for this period are available on the sites, please plan accordingly and deliver all content and metadata updates by Monday, December 15.

ePubs and Page Numbers

Because a standard ePub is a reflowable file type, it is like one long document. As such, it essentially has no pages. Therefore, a book with 170 print pages will not have 170 eBook pages or even 170 frames. There could be more or less depending on the devices. EBook viewers and devices such as Adobe Digital Editions, Kindle, Nook, iPad, etc. assign numbers that appear to be page numbers. If the numbers seem off, there is no cause for panic. The numbers do not and are not meant to correspond to print page numbers. Instead, they are for readers to gauge their progress and easily find their place in a book.

A fixed layout ePub, however, is made to resemble the layout of the print book and is not reflowable. This type of ePub has page numbers displayed in the file that correspond to those in the print book. A device that reads fixed layout ePubs, such as the iPad or iPhone, still shows location numbers at the bottom, but they may not correspond to the numbers on the pages if the front cover and frontmatter are counted as pages. (For example, one could click on pages 6-7 on an iPhone and be directed to a page numbered 4 because the iPhone reads the front cover, title pages, copyright page, and ToC page are considered pages 1-5.)
