In an embarrassing mistake, yesterday's item about Shelf Awareness's 20th anniversary omitted one of our newer staff members, publishing assistant Madison Gaines. Madison is hardworking and dedicated, juggling and placing thousands of ads in Shelf Awareness, and works with publishers to make their ads look as good as possible. Madison is often ready with a joke or riddle and enlivens the Seattle office. As a former bookseller at Third Place in Seattle, she has a good instinct for bookseller interests.
