I’m not going to lie to you folks—self-publishing your backlist isn’t for fun at all. It can be a tedious process, depending on the current format of your books, but it’s not all that difficult.
And you know what is fun? Making money off that backlist!
Don’t be daunted by the articles that cite self-publishing authors who only ever sell a hundred books. Sure, this is true, but this almost always applies to brand new authors. If you’re an established author with any kind of enthusiastic following, you will almost certainly sell far better than this. Probably much better.
