eBook Formatting Guidelines for Microsoft Word Documents
Some tips for how best to format your Word document to improve the look of your eBook:
• To create chapter headings, insert a Section Break at the beginning each Chapter. A chapter heading will be created for every Section Break in your document, so only use a Section Break where you want a chapter heading to be created. To insert a Section Break at the beginning of each chapter of your Word file, put the cursor at the beginning of each chapter and select [Page Layout > Breaks > Section Breaks > Next Page]. If you see extra chapter headings while reviewing your proof, it usually means you have extra Section Breaks in your Word document. To remove the extra Section Breaks, open up your original Word file on your computer and click [View > Draft] to display the Section Breaks, and then scroll through your document and delete all of the unwanted Section Breaks. When you're finished, re-upload your interior file.
• Bold, italic, underline and strike-through are supported.
• Internal and external links are allowed in your eBook, but note that customers may not be able to link out to external links while reading on NOOK.
• To decrease the space between your paragraphs when you convert from Word to ePub, you should only include a single return between your paragraphs. Adding extra lines will cause very large spaces between paragraphs.
• To increase the space between your paragraphs, you can use the Word paragraph tool to increase the spaces without creating excessive space. Adding extra lines will cause very large spaces between paragraphs.
• To indent your paragraphs, do NOT use the Tab key to create the indents. It is better to set up a first line indent using the Word Paragraph tool.
• To create a bulleted list, use Microsoft Word's built-in bulleted list tool. Do not insert symbols to create bullet points-most symbols will translate into a question mark ("?").
• To create a numbered list or multi-level outline, use Microsoft Word's built-in numbered list tool.
• Use one of the following fonts: Times New Roman, Arial or Courier New.
• Use Caps Lock to type in capital letters if you want text to appear in all capital letters. Do not use the Word format for All Caps.
• If you want small caps, type in capital letters and change the font size for the text area that you want to appear in small caps. Do not use the Word format for Small Caps
• Do not use columns.
• Do not use superscripts and subscripts, as they will cause extra leading (space between the lines of text).
• To indent a large portion of text, for example when creating block quotes, use Word margin controls.
• Images can be formatted flush left, flush right or centered.
• Text wraps should be above and below the images, not around the image.
• Avoid using most symbols.
• Ensure that any fractions are kept as "1/4." Word will automatically format the fractions to appear as symbols, which will not translate correctly into your eBook.
• Ensure that any ordinal endings are kept in line with the text ("1st") and not auto-formatted as superscript. Keeping them as superscript will produce added leading.
• Make tables that can be viewed in portrait mode rather than landscape mode to make them fit on the page
HTML Formatting Guidelines
A few tips to improve how your HTML file will look when converted to an eBook:
• Ensure that your HTML file is well formatted and renders well in your browser.
• Avoid adding any extra spaces between lines of text.
• Our NOOK eReading devices support the character set listed in our ePub Formatting Guide (available in the ePub Formatting section).
Note: Currently ZIP files are not supported in Barnes & Noble Press. HTML files that you provide should only include text, not images.
TXT formatting Guidelines
In order to ensure that your TXT file converts well into eBook format, consider the following:
• Format your text in paragraphs.
• Avoid including hard line breaks within your paragraphs.
• Use two line breaks to separate paragraphs. The first line break will end the first paragraph. The second line break will create a space between the first paragraph and the second paragraph.
• HTML tags should not be used. The HTML tag will be included as text during the conversion. For example, if you type <b>bold</b>, you will see the <b> instead of seeing bold

ePub is an open source, industry-standard format for eBooks. NOOK sells digital content that is in the ePub format. Because ePub is reflowable, customers can read files that are formatted in ePub on the NOOK dedicated eReading devices and on Android, iPad, iPhone, iPod, Windows 8, and PC and Mac via NOOK's free NOOK eReading software.
Publishers looking to sell highly formatted eBooks should convert their eBooks to ePub before uploading them via Barnes & Noble Press to ensure optimum formatting.
In this document, we provide background information on the ePub format and guidelines for optimizing your ePub to render well across the NOOK line of eReading products.
II. What is ePub?
As defined by the International Digital Publishing Forum (IDPF), ".epub" is the file extension of an XML format for reflowable digital books and publications. ".epub" is composed of three open standards, the Open Publication Structure (OPS), Open Packaging Format (OPF) and Open Container Format (OCF), produced by the IDPF.
More information on the ePub standard is available at the following websites:
Publishers not familiar with the ePub specification should follow the above links to learn more about the file format and container requirements.
III. ePub Requirements
ePubs are essentially "zip" files with a different extension. By renaming the file name of an ePub from "xyz.epub" to "xyz.zip, it can be zipped, unzipped etc. There are three fixed elements to every ePub file:
1. MIMETYPE file
2. META-INF folder
3. OEBPS folder
The MIMETYPE file occurs at the root level; both the META-INF and OEBPS folders occur below that. All other files can be organized as works best for the publisher. Two required files are CONTENT.OPF and TOC.NCX.
ePubs should be validated using EPUBCHECK (the latest version as of this writing is 3.0), available at http://code.google.com/p/epubcheck/. Instructions on how to use it are available here: http://code.google.com/p/epubcheck/wiki/Running.
IV. OPF specifications
The basic OPF file contains metadata statements, a manifest of included files and a list of the "playing" order of the files. While additional information can be supplied in the OPF that controls the behavior of other eBook readers, this is not a requirement for NOOK.
Metadata - The metadata starts with these three required lines of code. Note the unique-identifier declared in the second statement - this should represent a unique identifier scheme in use in your organization.
<?xml version="1.0" encoding="UTF-8" ?><package version="2.0" unique-identifier="PrimaryID" xmlns="http://www.idpf.org/2007/opf"><metadata xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:opf="http://www.idpf.org/2007/opf">
NOOK requires these statements:
AUTHOR <dc:creator>author name</dc:creator>
PUBLISHER <dc:publisher>publisher name</dc:publisher>
PUB DATE <dc:date>date</dc:date>
ID <dc:identifier id="PrimaryID">identification code</dc:identifier>
Manifest - The manifest identifies every file contained in the epub. If a file is not identified, it will not be accessible. Example of different file statements:
• <item id="pt" href="my_page.xpgt" media-type="application/vnd.adobe-page- template+xml"/>
• <item id="style" href="mystyle.css" media-type="text/css"/>
• <item id="image001" href="image001.jpg" media-type="image/jpeg"/>
• <item id="image002" href="image002.png" media-type="image/png"/>
• <item id="cover" href="cover_page.xhtml" media-type="application/xhtml+xml"/>
• <item id="toc" href="content_page.xhtml" media-type="application/xhtml+xml"/>
• <item id="ncx" href="toc.ncx" media-type="application/x-dtbncx+xml"/>
Note that item ID "toc" refers to the physical contents page while item ID "ncx" refers to the file that controls eBook navigation.
Spine - the spine controls the playing order of the eBook and determines which file precedes/follows another.
Guide - the guide is a list of references defining structural elements of the eBook (TOC, List of Illustrations, Index, Copyright etc). Use of guide elements is optional for NOOK.
V. NCX specifications
The NCX file contains the hierarchical table of contents and is represented by the Navigation Panel in Adobe Digital Editions. The listings in the NCX file are visible under the Table of Contents menu on NOOK. An NCX set to display in multiple levels will appear as:
VI. Image optimization
The screen sizes for the various models are as follows:
NOOK: 600 x 800 pixels (B&W - eInk)
NOOK Simple Touch/Glow: 600 x 800 pixels (B&W - eInk)
NOOK Color: 600 x 1024 pixels (Color - RGB)
NOOK Tablet: 600 x 1024 pixels (Color - RGB)
NOOK HD: 900 x 1440 pixels (Color - RGB)
NOOK HD+: 1280 x 1920 pixels (Color - RGB)
Images should be optimized for web delivery and can either be .png or .jpg. The choice of format is optional and should be based on a compromise of image quality and file size. Typically, .jpg supports a maximum of 16.7 million colors while .png supports 24-bit color. We recommend that cover images should be at least 1400 pixels on each side.
Content should be organised into separate HTML or XHTML files. For example, Title_page.xhtml, Contents.xhtml, Copyright.xhtml, Dedication.xhtml, Chapter_One.xhtml, Chapter_Two.xhtml etc.
Each file should be listed in the <manifest> of the OPF file. Files contained in the ePub but not listed in the <manifest> and files listed in the <manifest> but not contained in the ePub will fail epubcheck and may interfere with NOOK performance.
When defining styles in the CSS, margins should be set as "pixels", not "ems" or "% of ems". This will optimize the viewing area regardless of selected font or type size.
The page margins should be set at 30 pixels on the top and sides, with 20 pixels on the bottom. Embedded fonts are allowed: the publisher should own the right to include licensed fonts.
IX. Roman and Special Characters
NOOK supports the WGL character set. The set can be references here:
X. General eBook Conventions
• Covers are not mandatory in the eBook, but a Title Page is.
• The page order does not need to follow the print book.
• Blank pages should be avoided.
• It is helpful to have a Contents Page in the eBook, even if there is not one present in the print version. The eBook Contents Page is linked to the individual chapters and helps with eBook navigation.
• Ideally, footnotes should be linked.
• A linked Index is not necessary, but there is usually a disclaimer indicating that the page references are from the print version.
• The Copyright page should show the eBook ISBN, not the print ISBN, if available.
• HTML tabular layout should only be used for tables and not page formatting.
• The text in tables rendered as images cannot be searched.
