We squeezed EPUB export into InDesign CS3 before the final IDPF standard was approved, when even the name of the format was still in doubt ( thus the feature name: “Export for Digital Editions”). The just-released InDesign CS4 takes EPUB support to a whole new level, adding embedded font support and TOC generation (which we had made available as a separate update after CS3 shipped), as well as floating anchored images, option to emit CSS for local (non-style-driven) formatting, and improved mapping of TOC structure to XHTML heading levels. But the biggest feature by far is the new option to choose DTBook (aka DAISY XML) content within EPUBs, compatible with the NIMAS standard that has been mandated in the U.S. for providing access to K-12 instructional materials for the visually impaired. Our lead tools developer writes about the new features here, in our digital publishing tech blog. A very important next step on the client SW side is enabling “screen reader” support for DRM-protected eBooks, something we are committed to doing ASAP.
