It is possible to upload azw3 ebooks?
I'm not sure where this query should go, and hope that it will be moved if this is not the correct place.
Is it possible to upload ebooks in azw3 format to the MobileRead library? If so, where? So far as I can tell all the recent uploads in the mobi forum are mobi or prc. |

I believe JSWolf uploaded our first one - the first I've noted, anyway. HarryT would know more about the upload area.

I'll bring this question up (about recognized file extension and area to upload) in our moderator domain. |

IMHO, azw3-only files should be avoided, since only a limited number of devices and apps support them. Also, master mobi files that contain both regular mobi and KF8 segments aren't significantly larger if you use the -c2 compression option with Kindlegen 2.4 and strip off the source with the KF8 version of Kindlestrip.py.
If you need to use KF8, for example, for books that contain Hebrew or Arabic text, I'd recommend using Kindlegen 2.4 and replacing the mobi section with a warning stating that this file requires a device or app with KF8 support. (That's what I did with my English-Arabic .mobi file.) |

Thanks to you both.
Dreams - Jon uploaded to the other books forum, but I'll wait until it's been discussed by the moderators before I post any azw3 ebooks to the library. Doitsu - So far as I know only Kindle Touch and Kindle Fire readers read azw3, and I agree that that's a limited number of devices. But I don't think that necessarily means that only a limited number of people read azw3 ebooks, nor that there won't be more using this format in future. After all, if Jon can go to the dark side and use a Kindle then anything can happen. I'm the ebook designer for two small presses in the UK, and need to know when we should start supplying our ebook in azw3 as well as ePub and mobi - or perhaps if we start supplying our ebooks in azw3 format. If I do I'll almost certainly use calibre. Last edited by AlexBell; 06-01-2012 at 04:09 AM. Reason: Added the last sentence |

You should also consider that the vast majority of users, unlike the population here at MR, will not understand the difference between Classic MOBI and KF8 and thus giving them a choice will only be confusing. You should post single hybrid files leaving the user with only two choices; ePub and Kindle/MOBI. |

I see no problem uploading KF8 only versions. Why force people to have to download a bloated file they they have no need for 1/2 of it? Besides, in the case of The War of the Worlds we already had a good Mobipocket edition as I made it.

BTW, you're wrong as far as the file size is concerned. For testing purposes I compiled your ePub version of “War of the Worlds” with KindleGen 2.4 and Huffdic compression (-c2). After stripping the .mobi source files both files were almost equal in size: ePub = 1.96MB; mobi = 2.11MB For good measure, I did the same conversion in Calibre: mobi = 398KB; azw3 = 2.05MB As the numbers clearly show, it's definitely not the mobi part that leads to overly bloated files, because in most cases you could easily include the regular mobi version without a significant increase in file-size. |

In my past experience when creating mobi files, they used to be slightly larger than ePub. But sometimes the default mobi conversion implies reducing the size of all images, which results in much smaller mobi (and often much uglier).

Part of the reason for my initial query was to ensure that there would be minimal confusion for users of the MobileRead library. |

I uploaded a combo MOBI/KF8 ebook quite a while ago.
https://www.mobileread.com/forums/sho...d.php?t=145141 I don't really have much of a vested interest in how it ultimately gets handled, but there's something to be said for the fact that uploading combo files means nothing has to change from the current forum setup: no new subforum... nothing. The MOBIs in the MOBI forum would just slowly start gaining KF8 functionality. Those who know and care can always do whatever they want to the file anyway... and those who don't care won't have to mess around with inevitably downloading the wrong format and getting all cranky about it. Why reinvent the wheel for stand-alone KF8 ebooks? Also, I believe if a post has two attachments (one for mobi and one for azw3), it could possibly affect calibre's Get Books search feature. However it turns out... I believe one ebook attachment per post should be part of the procedure. |
