Yer right, the RCA Bible is a terrific compendium of information.  But Jonathan Valin is not associated with this magazine so there's a very low probability he will see your post.  Since the RCA Bible has been out of print for many years your best bet with respect to obtaining more copies is to check the book out again from the library and Xerox the Bejesus out if it.  I suppose it's possible an RCA Bible might pop up on eBay or Audiogon but I wouldn't hold my breath.  The last time I looked, about four years ago, the RCA Bible in good condition was selling for about a 100 bucks.
