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.

Book not showing up on Lulu
Hi, I published a book which keeps disappearing from Lulu searches. It is literally there one minute, and not the next. I know it's "really" there, because I can access it via my account, and reach it via the same URL when not logged in. But it (usually) doesn't show up when I type in the title and/or my name.
