Some of you were sticker-shocked at the price of what I consider the Bible of Old Time Radio, so I thought I'd post here another more popularly priced book, Carl Amari and Martin Grams "The Top 100 Classic Radio Shows"
I've read some of Martin's writings, and I've known Carl's work for some time. Now this book is limited in scope to just 100 shows, or should I say, 100 series, but for the price, you can sacrifice some of the less popular series and enjoy not only the photos but the three audio CD's that are included with the book.
If you're bargain minded and don't mind an older volume, Amazon still has used copies of John Dunning's Tune In Yesterday: The Ultimate Encyclopedia of Old-Time Radio, 1925-1976. This is Dunning's earlier and less complete version of On The Air.
If you want someplace to start, this is a good spot. For under $15, you can get some great reading.
