Not of interest to I. I don’t like hardcover. Harder, because of their weight, to read — & the added cost, just for a hardcover, does not make sense. Yes, it has cachet, status — but I do not see the point.
From what I can deduce we had to use hardcovers because books were bound with stitching. There were actual book binders. My adoptive father’s younger brother was that — a book binder.
But, then with better glue we were able to have durable paperbacks that did not fall apart when being read.
I am cool with just sticking with paperbacks. But, as you can see from the above image there are those that do want hardcover. So, they will be pleased.
KDP also now offers ‘Vella‘ — serialized books. I need to look into that. I might be able to use that.
