Sunday’s column starts with news from Rancho Cucamonga, from the departure of its top librarian for Pasadena to development items and more. Then come five Culture Corner items, one of which involves an Ontario concert with which I’m participating, plus a Valley Vignette.

As a behind-the-scenes tidbit, some of these RC items, just as with some of the Chino Hills items Friday, were written weeks or even months ago. This is a year-end move to take some material that has been bumped from previous columns, or saved for future use, and clear it out.
