If you see me on Tinker Street, or eating zucchini fritatas at Joshua's in Woodstock, you can ask me what the next book is--and if I know, I will tell you. (Often I don't know, because we haven't made a final pick until two or three days before the program airs). To publish the titles much in advance would be sort of against the spirit of book reviewing and public radio. 
I do love that the books we feature do well. I love that the authors and illustrators may get a nice check...if they have skillful publishers who exploit the exposure. Then there are the other kind of publishers, the kind I plan to expose to daylight in the near future. You know who you are, Marshall Cavendish.
