The Project Guide is your place to connect to our entire collection of Ohio 4-H project books for the year. Each project book contains information and activities for members to explore as an organized group project or at home under the guidance of a parent or interested adult. When choosing a project, consider your interests, background, what is necessary to start the project, and the resources available to help you complete it. 
Ohio residents can order project books and other publications described in the Project Guide through local county Ohio State University Extension offices. Out-of-state residents or Ohio residents who want to buy online can go directly to extensionpublications.osu.edu.
