You can still get recently published books like this! Usually only as small press signed limited or lettered (as in there are only as many copies as there are letters in the alphabet) editions that cost somewhere in the ballpark of $50-$250.
Discoverability when it comes to books is just hard. You can find out about some stuff online by following authors you're interested in, or conventions. But finding stuff you're interested in and enjoy is difficult, no easy way to go about it.

Checking out the vendor's room at genre conventions is another way to find out about cool books.
