As somebody interested in having your work in eBook form and possibly sold or distributed online one of the technical questions you would need answered is "what format should I have my eBook converted into?"
This, at face value, might seem like a technical forest you need to explore but luckily the answer recently has really been greatly simplified by the natural evolution of the eBook format Standards and eReader devices themselves!
A basic Google search on the topic will throw back terms such as PDF and KF8 however the answer (from people who have actually had work published) will be that there are only 3 formats to really pay attention to. Assuming your written work is in either MS Word or Adobe InDesign or PDF (if there is no other choice!) there are really only a few portals where you would want to be selling your eBook.
