MarketingSherpa has a book promotion opportunity for new books that relate to marketing, advertising, or publicity. You can read about it here.
If your new book relates to any of those areas -- and it's relevant to marketng professionals and a "good read" -- then you can send one copy of the book to Book Contest, MarketingSherpa Inc 499 Main Street Warren RI 02871 US. Include your contact information and the book's publication date.
If your book is chosen by MarketingSherpa's editors for their weekly Giveaway, then they'll request four more copies of your book. Marketing professionals can click here to register to win one of the books chosen for the Giveaway.
Your book competes with other books related to marketing for a book publicity opportunity, and marketing professionals compete with each other to win a free copy of winning marketing books. Sounds like a great idea to me, and a terrific book promotion opportunity for the right book.
