correct epubs are a matter of importance?
I observed that many epubs checked by epubchecker isn't valid because there are a lot of errors produced by this tool. But the epubs can be viewed without problems on my readers. So the question arise, whether the correctness of an epub according to the standard is important.

But you can never be sure. To reduce the probability, that the E-PUB will cause a crash somewhere out in the world, it's better to follow the standard. |

Correct ePubs are better because you can trust more on the presentation of the content. Incorrect ePubs are always interpreting on what the author could have meant and may vary from ereader to ereader or more worse from firmware to firmware on the same reader.

So there are two aspects of interest:
1. Do producers of ereaders really implement their firmwares in such a manner that epubs conforming to the standards are surely displayed correct? 2. If I test some ebooks from shops that sell them without DRM epubcheck also issued a lot of errors. So there is the question, how many epubs commercially sold are really formated according to the standards. (So that we will be able to read them using firmwares developed in 5 years ;-) ) |

To question 1, the answer is obviously "no". But if you have a compliant ePub that is not displayed correctly, you can blame the reader, whereas if the ePub is non-compliant, you cannot.

What standards? Many companies add their own bells and whistles to the format, which might then be seen as errors by the validators. Hopefully those are made in a way that don't cause harm to readers. So the errors might not be important.
Also, just because an epub is valid does not mean it's error free; there's still typos and formatting errors in them. The series I'm currently reading is like that (Skulduggery Pleasant, bought from Amazon because the epub shoppes refuse to sell outside UK/US). Fixing those content related issues is more important than insisting on standards, although it'd naturally be best to have both. |

I always try to have them error free and succeeded in that so far. That does not guarantee, unfortunately, that all readers display them as I want. However, that is because the readers don't honor the ePUB specifications.
If the ePUB contains errors, it is much more a hit and miss if the ePUB is rendered correctly. It might, but that is only because the reader is willing to correct errors which should not be there in the first place. It all depends on the actual errors. There might be structural errors (which I feel must be corrected), files in the ePUB which are not used (easy to solve, gives bloat in the file), wrong references (mostly annoying) or new stuff which might be correct according to ePUB3 but not in the checktools yet. |

Look around in the forums here ! A few days ago i stumbled over some queries from an epub-maker. From his questions i could see that he uses some kind of software to produce the book and his sole problem was the checking-software of the dealer. Finally he managed to pass the test somehow (I guess with some help frome here). You may buy the book by now for 6.95 EUR. |

But we are in the same discussion now with HTML in former times. All website designers were asking "Why should i do the w3c validator check? its full of errors, but in IE4 its displaying fine!". And with IE6 they were forced to change their coding... And of course, passing the valditor does not tell you that there are still errors: the images might be distorted, the internal TOC is missing and so on. I do not understand why there are still so many ePubs having structural errors and why it is over and over again a discussion worth if those errors should be corrected or not. In most cases less time is needed to correct the error as the discussion itself is consuming. I really would prefer that every reader has a validator built in and refuses to display erranous ePubs. |

But a built-in validator which shows the customer what bugs he has payed for, would be fine. This will encourage more peaople to complain... Last edited by mmat1; 02-27-2012 at 01:22 PM. |

I actually had my reader crash multiple times before I tested the book I was reading. Needless to say that it failed miserably.
