My best results for blurbs for all genres--poetry to how-to
nonfiction books--has been from what some call fan letters but I just call
communication with my readers. People seem to be more effusive when they are
writing e-mail or letters they have no idea might be reprinted. The idea of
words being published seems to make people's prose stiff and less readable or
memorable!
I copy and paste the part I'd like to use as a blurb back to them
and ask permission. Then I ask how they'd prefer to be credited. The last
part of that question is important because it lets them know that providing the
quote can help their exposure to the public, too. (-:
The downside to this method is that one doesn't get fan mail until
after one is published, so it must be supplemented with the tried-and-true
method of asking folks upfront to collect enough blurbs needed for the
book's cover, and for the pre-publish media kit.
OK. If this seems familiar to you, I admit I cribbed the idea from
my own Frugal Book Promoter (http://budurl.com/FrugalBkPromo).
But the question came up in a communication from Independent Book Publishers
Association so I thought I'd share my take on it. And if you need help with getting blurbs pre-publiciation, you'll want to read the chapter on query letters in The Frugal Editor and turn to the appendix for examples of different kinds of query letters. (http://budurl.com/TheFrugalEditor).
