I'm re-releasing my first book with a new cover, some minor edits, and bonus content but I'm getting tripped up with whether I need to call this a second edition or a revised edition. Is there a difference? What do second editions usually entail and are they usually seen in the fiction world?
How much do I have to change in my own work to make a new claim of copyright?
You may make a new claim in your work if the changes are substantial and creative, something more than just editorial changes or minor changes. This would qualify as a new derivative work. For instance, simply making spelling corrections throughout a work does not warrant a new registration, but adding an additional chapter would. See Circular 14, Copyright Registration in Derivative Works and Compilations, for further information.
I've seen notices on the copyright page that say something like "an earlier version of this book was published in X."
I think I’m a little confused about what first edition means. If a book says it’s a first edition doesn’t that mean it’s the first printing?Nope.
Editions are revisions to the whole book
Here's a photo of the cover of my trusty Merriam Webster.
Notice it's the 11th edition.
That means that this dictionary has been revised and updated 11 times.
You want the eleventh, not the seventh, edition so you'll know what hashtag now means!
And here's a picture from the copyright page.
Notice it's the 22nd printing.
Each print run is a printing.
Printings and the size of the print run do not bear any relation to the content of the book.
It's a function of demand for the book.
If no one buys the 22nd printing (saturated market) there won't be a 23rd printing.
If aliens arrive and lots of new words enter our vocabulary, there will be a 12th edition.
