Here's a great web site:
They boast "Visit Authors Access podcasts: www.authorsaccess.com where authors get published and published authors get successful."
I've listened to many of the podcasts and they are so helpful and interesting.
I just listened to one about the importance of book covers featuring Patrick Snow who has "spent over ten years of his life developing this unique system that is designed to save you both time in money in your quest to achieve your publishing and book promotion goals". His web site is here and I strongly urge any author or author-wanna be to check it out.
