I've seen them done on EPUB (it's doable, since it's HTML based, it at least has the features).  But Amazon's MOBI format fails miserably, which is why they put PDF in the Kindle DX, imo.<br/><br/>Josh<br/><br/><br/>May 10, 2009 01:12:25 AM, gutvol-d@lists.pglaf.org wrote:<br/><br/>===========================================<br/><br/>For at least two reasons I can think of.<br/>First, at least in my experience trolling for ebooks on the web, pdf files predominate by a wide margin.Second, it's interesting how almost all sample texts are novels, where page composition is so much less demanding. Yet at least half my ebooks are technical, and pretty much all pdf. Has anyone else had the test case experience with googled sources, where matches offer the text in multiple formats? And how the only satisfactory option seems to be pdf; and how unsatisfactory html is? (I've never seen a technical document offer EPUB in the wild.)<br/>On Sat, May 9, 2009 at 6:01 AM, Marcello Perathoner &lt;marcello@perathoner.de&gt; wrote:<br/>Jim Adcock wrote:<br/><br/><br/><br/>I'm starting to believe PDF can beat EPUB on portable reading devices.<br/><br/>You cannot scroll on the Sony Reader, just flip pages, and your screen size is fixed, so a pre-paged format makes more than sense.<br/><br/>Also, footnotes are a real PITA with EPUB. The link is hard to follow without a mouse and they mostly end up in a different EPUB flow, so they take an eon to load and another one to get back.<br/><br/><br/>_______________________________________________<br/>gutvol-d mailing list<br/>gutvol-d@lists.pglaf.org<br/>http://lists.pglaf.org/mailman/listinfo/gutvol-d<br/><br/><br/><br/><br/>_______________________________________________<br/>gutvol-d mailing list<br/>gutvol-d@lists.pglaf.org<br/>http://lists.pglaf.org/mailman/listinfo/gutvol-d<br/>
