In awe of copy editors

I spent today on the second round of pickups for two books I'm editing, going through the copy editor's comments. The modifier holographic came to mind as I marveled at how this person surfaced the tiniest details for inspection. Putting these books together is like working on a Ducati - not that I've ever done so myself, but an amateur mechanic of my acquaintance once told me that rebuilding one was his most daunting project: "A lot of moving parts."
