I'm not sure if this is the right place to post this or not, but here goes nothing.
I've been thinking about starting a multi-author box set in order to build an audience. I have a few short stories published, and a novel on submission to agents, but I want to do more to create a stronger platform for myself. Would starting a multi-author box set help? I've never self-published, so I've been searching all over for information on how this is done, because I don't want to step into anything without knowing what I'm getting into.
I've been looking around Amazon and Smashwords, and noticed that there are a few non-romance author bundles, so I don't think the genres I write in would be a major problem (I write fantasy, horror and science fiction).
Would publishing a bundle help with my platform?
