Looking for something to do over Labor Day weekend? You could take this $47 Udemy course on producing ebooks. Offered by DigitalPubbing.com’s Sabrina Ricci, who’s also a self-published author, it breaks down ebook production — including coding, file formatting and specific retailer instructions — into 25 parts. Note: I haven’t taken the course. And some reviewers complain that the volume on the first 8 lectures is too low, though they give the content high marks. It can be tough to find all this information in one place online, so it seems as if the course could be a good resource.
