We're aware of an issue with converting some DOC, DOCX, ODT, and RTF files to EPUB through our Ebook Wizard.

At this time, we're investigating the problem and looking for a solution.

If you've encountered this issue while converting your file, we suggest attempting to create and upload an EPUB directly to our system.

While there are a number of EPUB conversion options, Calibre (Download Here) has shown the best results for creating an EPUB for the Lulu system. Please review their extensive Help resources (Found Here) to create an EPUB 2 that our system can validate.

We've also created this Forum Thread. Post questions here and we'll do our best to respond and assist.

We’re bringing the site down for maintenance tonight.
 
Lulu.com, Lulu xPress, and Lulu Jr. will go offline at 12:01 AM on Thursday, October 25. We expect this maintenance to last about six (6) hours, until 06:00 AM Eastern Standard Time. (05:01 AM to 11:00 AM in London and 02:01 PM to 8:00 PM in Sydney, Australia).

Question on custom ISBNs and eBook formats

I already have my own ISBNs and I'm looking to publish in ebook format and sell to multiple outlets. But I'm confused on one point. How is it possible that a Lulu project with a single ISBN can be distributed to channels that can't (or shouldn't) reuse the same ISBN?

 

From the video tutorials I've seen, it looks like for a new project I can: 1) provide my own ISBN, and then 2) distribute to different outlines (for example, EPUB edition for iBooks and MOBI for Kindle). But I don't get how that can work.

    Electronic is one format. Paperback 6x9 is one format. Hardback 6x9 is one format.

     

    One could posit that if the Epub and Mobi file have the same distribution origin point, it would be considered the same format even if tweaked slightly to operate on different devices.

     

    Lulu employess should be in the office tomorrow to provide a more technical answer, since this is Sunday.

  • Sphinx is right, the ISBN is attached to the specific edition and format. For eBook there is a slight allowance here between EPUB and MOBI, primarily because Amazon insists on using the MOBI format rather than doing what every single other ebook does and use EPUB.

    So MOBI is a bit of a special case, but the way to think about it is like this: When you create an ebook on Lulu, we're distributing the EPUB book, with the caveat that distribution to Amazon allows for them to convert to MOBI.
