The last few weeks have seen a tremendous increase in interest about ePub. Many new blog posts have been written trying to explain the format. We’ve also seen a big jump in the number of publishers coming to Threepress for help with tricky ePub problems or just asking for guidance about the format. While I’d [...]

Obviously I’m a fan of the ePub format. It’s flexible enough to support advanced publications, but a simple text ebook can be put together with minimal effort.
But I don’t think it’s minimal enough. If I could go back in time and be involved with ePub and its predecessors, here are the choices I’d make:
Make [...]
The ePub format allows for a fairly comprehensive set of book-friendly metadata, mostly drawn from the Dublin Core set of terms. Knowing what metadata to use and how it will appear in today’s and tomorrow’s readers is key; here are some recommendations:
Authorship
Two elements describe authorship of a work: dc:creator and dc:contributor. As you might [...]
The vast majority of ebooks today have print cousins, despite some recent digital-only publishing news. As a consequence, many people creating ePubs want to know how to tie references to the printed pages back into the ebook. My personal opinion is that this sort of print-centrism is unnecessary for the vast majority of titles1, but [...]
InDesign CS4 is one of the most popular tools for creating ePubs, but the range of options it provides when exporting can confound many users. While I’m not a wizened InDesign expert, I have accumulated a set of choices for the various options that differ from the defaults and can help form the basis of [...]
Languages aren’t just written right-to-left or left-to-right, of course. They can also be written top-to-bottom, as in Chinese. How can you indicate that a block of text should be rendered vertically rather than horizontally?
In ePub, you can’t.
I was surprised to discover that the subset of CSS supported by ePub only includes the rtl or ltr [...]
Languages such as Arabic and Hebrew are written right-to-left (RTL) rather than left-to-right (LTR), as in European languages. When dealing with only one of those scripts at a time, computers generally handle the directionality well by just falling back on the user’s general language setting. But what if you have to render text in multiple [...]

The three ePub specifications (OPF, OPS, and OCF) include a lot of detail on ebook metadata and markup, but do not include a technique for describing covers. Despite this omission (a fix is being discussed), there are some widely adopted approaches for marking up covers that will [...]
If I say that a document is in “XML”, I’m not really saying anything very specific. All I’ve told you is that the document has some text wrapped in various angle-brackets, and that those angle-brackets are “well-formed.” A well-formed XML document just means one in which the angle-brackets open and close in a predictable [...]
