Any New Books?, Antonio Cangiano, Founder. Email: email@example.com. - Features notifications to users of new books in various subject categories. They have a simple editorial policy: With the exception of areas that will be clearly marked as advertisements, all the content of our newsletter has been selected and curated by us, not by our advertisers/sponsors. This assures you that a book will appear solely in a weekly email on the grounds that it’s interesting and new, not because of some behind the scenes deal with a publishing company.
AuthorBuzz - Email: firstname.lastname@example.org. Puts authors in touch with 365,000 readers, 12,000 librarians, 5,000 booksellers, and 14,800 leaders of bookclubs.
