Created by a collaboration between more than two dozen agencies such as the White House Office of Science and Technology Policy, the Federal Crowdsourcing and Citizen Science Toolkit is an invaluable source of information for aspiring or continuing citizen scientists. This central information hub offers plenty of wisdom, "including success stories and some of the challenges that developers faced in designing and carrying out citizen science and crowdsourcing projects." The toolkit also provides articles, tips, examples, and more, divided into three main categories: Getting Started, Case Study Overview, and Resource Library. Those new to citizen science may want to begin on the Getting Started page. Here, readers will learn about the five basic steps to design a successful citizen science project. From there, readers can build upon their knowledge with many of the other in-depth resources. There is also a Law and Policy section (accessible via the Toolkit dropdown menu) that contains many important considerations. The toolkit was released in 2015, but readers will find more recent resources on other parts of the site. For example, CitizenScience.gov's Blog (found under the tab in the top-right corner) contains posts as recent as July 30, 2019.
