Wipers, thank you for responding to my post. I can't believe my original post has had almost 1,000 views and nobody knows of his book I'm looking for. Damn, I'm either really old, or I'm imagining things.
Regarding searches in Amazon or Wikipedia, if you don't know the author/title, just type in key words that might describe the book you seek, and hit the search button. In my case, for the book I'm desperately trying to find, I type in things like "children's science fiction - saturn - space - buzz", etc.
Then again, this obviously hasn't worked for me yet, so if anyone else has a fine idea, I'd love to hear it too.
What are you looking for, Wipers? I'll try to help you if you do likewise for me.
