Zonal Clipping Headers

The maintenance on my zonal pages, outlined in Zonal Index Update, then completed for Inventory of Missing Zonal Clippings and Zonal Months, took another step forward. I compared the index page World Chess Championship Zonals with the clipping pages listed at the bottom of the index, resolved as many header discrepancies as I could, and updated 19 clipping pages. I'll perform the comparison one more time before I update the index page.
