This is easy: we love books!
I’m a biblioholic and if you’re like me, you spend lots of money on books and they feature in your everyday life as escape, entertainment, learning, and pleasure. I grew up devouring books in the library and asked for books most birthdays. I go to my local bookstore several times a week and buy books almost daily online.
The physical book likely holds a powerful sway over you, so you should publish a print book for the joy of holding it in your hand and saying, “I made this!”
But you should also consider print from a business perspective because if you get emotional about it, you might find it will cost you a lot of money.
There are a number of good reasons to have a print book.
Many readers still prefer print books, so if you don’t have one, then you’re missing out on that market, especially in print-heavy genres like non-fiction, poetry, children’s books and more.
They are useful for marketing and giveaways to readers. It's hard to send a signed copy of an ebook, although it can be done through Authorgraph.
They are great for comparison pricing on the online bookstores because it makes the ebook look like a great deal due to the perceived reduced price. For example, my book Crypt of Bone is $11.99 in paperback and $4.99 on Kindle, so the reader can save $7, or 63%. A bargain! I also have Large Print and hardback editions as well as an audiobook, so the reader has a lot of choice.
