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.
Is Lulu appropriate for a small publishing business?
Many small publishers use Lulu. Advantages of using Lulu include the competitive cost of professional printing in small quantities, order fulfillment and royalty tracking, a free storefront of your own, access to online bookstores, and great search engine visibility for your products.
We require everyone who publishes through us to have the legal right to the material. This might require model releases in addition to copyrights and permissions.
