I'm working on publishing my late father's writings as eBooks. You can read more about it in
my thread in the Author Self-Promotions forum.
I have 8 volumes to publish although I still have to go through them all to edit and format. I've read that one of the best ways to promote is to have multiple books that link to each other.
Would it be better to just put them all out as soon as possible or take my time and release them one at a time and let each book build interest? I'm kinda thinking every other month at this point but I don't know.
