14, Developer Preferences for Reading eBooks 25, New site Kindles - the developer's take 40, Nook subscribers to get free access to NYT website. EPUB is an XML-based, developer-friendly format that is emerging as the de facto With freely available software tools, you can bundle Web pages as EPUB, .. This usually means a list of XHTML files that make up the text of the eBook plus. Download ebooks (pdf, mobi, epub) and read online. object-orientation, test- driven development, database handling, web frameworks, and much more.
Currently EpubPress is a free tool I've developed in my spare time. Hosting this service is paid for entirely out of my own pocket. You can help keep EpubPress alive with your donations. When a book is created, the html from your selected tabs will be sent to a server for publishing into an ebook.
When an ebook is requested, your email will be sent to the server if provided. This is necessary for email delivery and will not be used for any other purposes. If no email is provided, the ebook will be returned as a file and no information about who requested the book will be saved. All extension code is available here. Extract of an OPF guide The guide is a way of providing semantic information to an EPUB reading system.
While the manifest defines the physical resources in the EPUB and the spine provides information about their order, the guide explains what the sections mean. Here's a partial list of the values that are allowed in the OPF guide: cover: The book cover title-page: A page with author and publisher information toc: The table of contents For a complete list, see the OPF 2.
This is rarely a problem when you generate EPUBs programmatically, where the same code can output to two different files. Take care to put the same information in both places, as different EPUB readers might use the values from one or the other.
Although the OCF file is defined as part of EPUB itself, the last major metadata file is borrowed from a different digital book standard. DAISY is a consortium that develops data formats for readers who are unable to use traditional books, often because of visual impairments or the inability to manipulate printed works.
The NCX defines the table of contents of the digital book. In complex books, it is typically hierarchical, containing nested parts, chapters, and sections. Listing 8.
This element should match the dc:identifier in the OPF file. This example has only one level, so this value is 1. It's okay to be confused, as both files describe the order and contents of the document. The easiest way to explain the difference is through analogy with a printed book: The OPF spine describes how the sections of the book are physically bound together, such that turning a page at the end of one chapter reveals the first page of the second chapter.
The NCX describes the table of contents at the beginning of the book. The table of contents always includes all the major sections of the book, but it might also list sub-sections that don't occur on their own pages. The navMap is the most important part of the NCX file, as it defines the table of contents for the actual book.
The navMap contains one or more navPoint elements. Each navPoint must contain the following elements: A playOrder attribute, which reflects the reading order of the document. This follows the same order as the list of itemref elements in the OPF spine.
This is typically a chapter title or number, such as "Chapter One," or—as in this example—"Cover page. This will be a file declared in the OPF manifest.
It is also acceptable to use fragment identifiers here to point to anchors within XHTML content—for example, content. Optionally, one or more child navPoint elements. Nested points are how hierarchical documents are expressed in the NCX. The structure of the sample book is simple: It has only two pages, and they are not nested. That means that you'll have two navPoint elements with ascending playOrder values, starting at 1.
In the NCX, you have the opportunity to name these sections, allowing readers to jump into different parts of the eBook. Adding the final content Now you know all the metadata required in EPUB, so it's time to put in the actual book content. You can use the sample content provided in Downloadable resources or create your own, as long as the file names match the metadata.
Next, create these files and folder: title. This file can contain any CSS declarations you like, such as setting the font-face or text color. See Listing 10 for an example of such a CSS file. Use this sample for your title page title. Listing 9. Sample title page title. Use IDs to refer to anchors within content. Listing 10 demonstrates a simple CSS file that you can apply to the content to set basic font guidelines and to color headings in red. Listing Sample styles for the eBook stylesheet.
If you create technical documentation, this is probably not relevant, but developers who build EPUBs in multiple languages or for specialized domains will appreciate the ability to specify exact font data.
You now have everything you need to create your first EPUB book. In the next section, you'll bundle the book according to the OCF specifications and find out how to validate it.
This bundle will either be a new book that you created yourself or one that uses the raw files available from Downloadable resources. The mimetype file must not be compressed. The ZIP archive cannot be encrypted.
Using ZIP version 2. These commands assume that your current working directory is your EPUB project. In the second, you add the remaining items.
The flags -X and -D minimize extraneous information in the. Make a final check with the EpubCheck package see Related topics. It is a Java program that can be run as a stand-alone tool or as a Web application, or you can integrate it into an application running under the Java Runtime Environment JRE version 1. Running it from the command line is simple. Listing 12 provides an example. Sample errors from EpubCheck my-book. All of these will create ePub files that work, and that should be accepted by most retailers.
Well, there are a couple of things. The apps will try to reproduce on the screen what you were trying to create for the printed page, but often the style rules that the apps try to create make an incredible mess in one or more ereader. Everything may display as plain text on a Nook, while small images may fill the page on an old Kindle, while no images display at all on the Kindle app on your computer. Also, all of these programs have idiosyncrasies; most create ePub files that are very difficult to customize, since they treat any style change italics, font size, indents, etc.
If you use the Styles formatting rules that all of these apps allow — apply a Body style to all body text paragraphs, for example, rather than formatting them as 12pt. Palatino and hitting the tab at the beginning of every paragraph — the results will be better, but inevitably the ePub file produced this way contain WAY too much code, enough to swell the file size.
But you can format the text and even insert images, hyperlinks and the other paraphernalia that make up an ebook, and then use an app to convert the document into ePub format. There are also a number of ways to upload a Word document and get an ePub file. Most of them fall under the paid conversion option, which comes below.
