Should I retire the first edition? When?
My book has sold a few hundred copies, and is still selling on Lulu and Amazon.
I've completed and released a second edition, substantially extended, new ISBN. Review copy has gone out. It's available on Lulu and now appears in Amazon search.
I think I should retire the first edition now. Is there any reason not to? The only thing is: reviews. Amazon reviews (all positive!) are attached to the first edition. Second edition has no reviews at all. Does this matter?
Any reason not to click "Retire" right away?
