A couple of decades ago, when I worked as an editor at a university book publisher, it was all about galleys. First galleys, second galleys. Send 'em to the author. Hound the author to send 'em back. Call the author if her corrections were illegible or illogical.
But in my book-writing experience, there have been no galleys. I turn in my manuscript. I hear nothing. I forget about the whole thing and move on to other projects. Then one day my free copies of the finished book show up at my door (or they don't, as happened once, when I found out two years later that my book had been released).
I miss galleys.
