Tbh i've given up on dead tree books with the lone exception of a few hard covers because ... space the final frontier.

(trade paperbacks are the larger paperback editions printed on better paper than the mass market paperbacks, but still soft-cover.)
John Scalzi posted about this a few months ago:
"All my recent books went from hardcover to trade paperback and almost all of my backlist in mass market has now migrated to trade. The role of mass market paperbacks is now handled almost entirely by ebooks."
I used to prefer trades but have gone all in on mass market editions. They just feel better in my hands, especially larger volumes. Plus I can stuff it in a coat pocket on my way out the door.
And FWIW, I’ve found that the “printed by Amazon” editions have actually been higher quality than recent offsets. For example, the newest editions of Hitchiker’s Guide seem to have been laid out without any regard to the inner margin. It’s fiddly to read the first word on each line.
Meanwhile the Star Wars Legends mass markets fulfilled by Amazon in Italy and France have thicker, brighter, paper and clean margins.
For the mass market format, I have to take what I can get, and I’m glad that there are still reasonably priced editions available.
