The Open Notebook (TON) is a science journalism non-profit organization, online magazine, and publisher. Its purpose is to help science journalists improve their skills. It publishes articles and interviews on the craft of science writing and maintains a database of successful pitch letters to editors. TON also runs a paid fellowship program for early-career science journalists. The Open Notebook is supported by foundation grants and individual donations, and also partners with journalism and science communication organizations. Description The Open Notebook was founded as a 501(c)(3) non-profit organization by freelance science journalists Siri Carpenter and Jeanne Erdmann. Initially, its sole purpose was to publish "story-behind-the-story" interviews with journalists about the genesis and development of specific published pieces of science journalism. Subjects of interviews at The Open Notebook have included Rebecca Skloot, Kathryn Schulz, Ed Yong, Mary Heglar, Elizabeth Kolbert, Steve Silberman, Adriana Gallardo, Carl Zimmer, Ankita Rao, Nicola Twilley, David Quammen, Christie Aschwanden, Elizabeth Shogren, Natalie Wolchover, Seth Mnookin, Cynthia Graber, and Gabriel Mac. In 2011, Carpenter and Erdmann expanded the project to include a pitch database, an advice column, and articles on topics such as structuring narrative feature articles, finding and sharpening story ideas, taking good notes as a reporter, and pitching story ideas to editors. Knight Science Journalism at MIT wrote of the organization: Gary Price of Library Journal said The Open Notebook "provides unique tools and resources to help science journalists at all experience levels hone their craft". Spencer Davis of The Freelancer by Contently said TON's site "was built for science journalists in particular, but many of the site's resources are just as applicable to all freelance writers". Tara Haelle of the Association of Health Care Journalists wrote, "Perhaps the best science journalism site/blog out there is The Open Notebook, chock full of advice, tips, guides and inspiration." She listed the organization of topics on the site: "Breaking In; Finding Ideas; Pitching; Story Planning and Reporting; Writing Accurately, Clearly and Engagingly; Fact-Checking, Self-Editing and Revising; The Business and Economics of Freelancing; Being Part of the Science Journalism World; and Looking for Inspiration?" David Dobbs, writing in Wired, called TON "The wonderful shop-talk site for science writers."
