EPUB EPUB (short for electronic publication; sometimes styled ePub) is a free and open e-book standard by the International Digital Publishing Forum (IDPF). Files have the extension .epub. EPUB is designed for reflowable content, meaning that an EPUB reader can optimize text for a particular display device. EPUB also supports fixed-layout content. History[edit] EPUB became an official standard of the IDPF in September 2007, superseding the older Open eBook standard.[3] In August 2009, the IDPF announced that they would begin work on maintenance tasks of the EPUB standard.[4] Two broad objectives were defined by this working group: "One set of activities governs maintenance of the current EPUB Standards (i.e. On April 6, 2010, it was announced that a working group would form to revise the EPUB specification.[6] In the working group's charter draft, 14 main problems with EPUB were identified, which the group was to address.

mgylling/epub-testsuite Controlling spreads in EPUB3 Fixed Layout EPUB 3's spread settings should allow you to decide when individual documents are placed next to each other on a 'synthetic' spread in a book. For example, you might want to show two consecutive pages in a spread if the device is held in landscape orientation but individually if it's held in a portrait orientation. According to the spec, that's possible. In real life, on real devices, it's not. Let's look at the different options, since they're not very self-explanatory. First, you can find a quick overview on this earlier article about EPUB 3 fixed layout. EPUB 3 has three important fixed layout rendition properties, layout, spread, and orientation. <meta property="rendition:layout">pre-paginated</meta> And if you want a flowing book, you'll leave it out to use the default value of reflowable. The spread property determines when pages should be placed next to each other in a 'synthetic' spread. So, for example, here's what it looks like in iBooks if you choose none.

Handle.Net Registry ePUBSecrets Getting rid of faux pages and binding in iBooks Apple's iBooks has been accepting EPUB3 documents for some time, which means they can now benefit from EPUB3 features. One of those features is whether or not the binding should be displayed, which in iBooks takes the form of a faux spine: To make the faux spine disappear, you simply have to add this line to the <meta> section of your opf file (in an EPUB 3 fixed layout file): <meta property="ibooks:binding">false</meta> And as long as you have version 3.1 or later of iBooks, the faux binding (and the faux pages at the edges) disappear: Note, however, that if you designed your pages to fit perfectly in a landscape-oriented iOS device, the disappearance of the faux pages will make your book slightly more narrow, and you will have some empty gray space as shown above. (Thanks to Jean-Michel Dentand for reminder to update to new version of iBooks!)
