ePub vs. pdf
jellby has posted a very succinct resume of the different strengths of epub and pdf in this thread, and i thought it would be appropriate to add it here since it's a question which arises frequently.
the original poster wanted to know whether epub could rival the complex layout features of pdfs, and why it's a better format in general for ebooks. Quote:

EPUB - What a difference a year makes (18 min video)
A presentation from BookNet Canada Technology Forum, Toronto, March 2009.
Michael Smith's presentation on EPUB ~ What a difference a year makes ~ Adoption of a Digital Standard Mr. Smith needs a bit more practise doing presentations, but some interesting stats and graphics shown. I was almost expecting to see Calibre mentioned in one of his charts regarding conversion, but alas, no. (Mr Smith is executive director of the International Digital Publishing Forum - I'm not sure if he is connected to Hachette or not.) 18 minute video presentation: http://blip.tv/play/AfyRNZWAGA (*Note - this was posted as an afterthought in another article in the "News and Commentary" forum titled 6 Projects That Could Change Publishing For the Better, but I thought it might get lost so I've reposted the link to the EPUB presentation again in this thread.) Other presentations on publishing (both eBook and pBook) at the BookNet Canada Technology Forum 2009 are at this link. http://www.booknetcanada.com/mambo/i...374&Itemid=276 Last edited by Wetdogeared; 05-13-2009 at 01:26 PM. |

More eBooks added to Norman library
http://www.newsok.com/more-ebooks-ad...rticle/3370944
Pioneer Library System has expanded its selection of electronic books available through its virtual library. The library system added Adobe EPUB eBooks that are compatible with the Sony Reader devices. Library cardholders can access the virtual library through Pioneer’s Web site, www.pls.lib.ok.us. An eBook is a digital version of a print book that has been formatted for on-screen reading. It is viewable on a computer or can be downloaded to a portable reading device. |

I'm reading this at http://www.idpf.org/2007/ops/OPS_2.0...l#Section1.3.5 anyway... one thought that occurred to me while reading this thread is: why would epub be difficult or "computationally expensive" for any portable device that isn't ancient? epub is simply xhtml and css--the same as any webpage. however, because epub doesn't have javascript, flash, or nearly as many images as a webpage, i would imagine it would render faster than a webpage. also, smartphones and such--portable devices--can display webpages just fine, including reflowable and resizable text on a variety of screen sizes (and sizes of browser windows). so why would an epub be any different? extending that thought... why is creating an epub reading system so difficult? epub files are basically just simple webpages of text. any reader just has to use a copy of webkit or gecko or some other open-source renderer to make an epub reading system that supports far more advanced things than are required by the epub specs. reading systems may perhaps simply need to add a few "hacks" to create reader-specific thing, perhaps something related to pagination or whatnot. |

I believe that correctly implementing SVG, which is a part of the ePub standard, is complex and computationally expensive.

true, svg might be a bit hard for weak processors. however, at this time, i think it's safe to say that svg in ebooks is pretty uncommon.

And SVG support in ePUB readers (even desktop readers) seems to be rather poor anyway.

Hi! I've been reading the posts here for the first time because i just got my new Sony 600 reader and Sony sent me a message that they're switching to Epub for the books they sell and I wanted to know how it's different from .pdf, which I've been using for the books I've downloaded from Gutenburg. Is it actually better than PDF and if so, how? Can I use it for converting books from Microsoft format (I haven't figured out that one yet), and will it support color? I ask this because I know that Sony has been working on a color reader for at least 5 years and since I like to read gardening books, color is important to me.
I've found much of the discussion here pretty technical (I'm a beginner at this topic), so please keep it fairly simple. What is DRM anyway? Folks keep referring to it. Well it's interesting reading your comments, and I'll be back! -Fringecup |

An ePub book is basically a collection of HTML pages in a "wrapper" and, just like any web page, it can adapt itself to different sized screens by "rearranging" itself (this is called "reflow") to fit the screen. It's a much, much better idea when you're dealing with devices with differently-sized screens. Plus, you can change the font size and do all sorts of other things that you just can't do with a PDF file. Quote:

Harry, I'm curious why DRM doesn't bother you. Is it that you don't normally want to pass your books on to other people? Or, is that you know how to remove the DRM without much effort? Or do you think people should pay to read a book every time? Or is it something else entirely?
(Yes, Zelda, I know this is somewhat off topic, but since I just spent an hour reading this whole thread, trying to digest the epub info in order to figure out which way to go with my Cybook upgrade, I feel "entitled" - ) |

One reason to go ePub is portability. If you decide to get another reader, as long as it supports ADE, you can take your ePub with you and keep reading. It's that easy.
