First, it would seem that I will need to copyright each article separately since some have been released and I do not have them all written in advance. Second, I'm concerned with this statement on the US Copyright Office website regarding online works:
Many works transmitted online are revised or updated frequently. For individual works, however, there is no blanket registration available to cover revisions published on multiple dates. A revised version for each daily revision may be registered separately, provided the revisions constitute copyrightable authorship. A separate application filing fee would be required for each separately published update.
Since I may be updating these articles before creating the e-book I'm wondering what advantage the registered copyright will have given all the potential updates and what could be an expensive process ($30 per registration).
And what registering does for you is allow you to recover statutory damages in the event of infringement--meaning real money.
Others may correct me on this, but I believe that you'd be in good shape if you just registered all the articles when they were done....
