How to edit my already published book?
Since I had someone else navigate my book throught the lulu process, I do not know how to get in and make the few small edits that I now wish to make before announcing my book to the world. I have all of the files he left me with. What is my first step? How do I get into the text of my book? Is there a tutorial someone can direct me to? I should be able to make these edits in about 10 minutes, but have been putting it off, for a couple of months now, because I don't know how to navigate around, upload, etc. Thanks.
