Query: Still Good After All These Years

I purchased this edition to replace my well-worn copy which I have had for 45 years.I was delighted to find that there were many updates such as planetary information(including the demotion of Pluto!), some changes in star brightness, and otherreflections of advanced knowledge. I still find it incredibly useful, particularlysince my move to the Southern U.S. which has allowed me to see "new" stars.
