Content, such as archive items, trails and articles, on the site can be shared to Facebook, Twitter, Tumblr and Pinterest. These are represented by a set of badges near the top of a sharable page. Click on the badge for the platform you wish to share to. This will link you to that platform. You may be asked to login to the platform and format how to share the item. You do not have to be registered with the site to use these but you will need an account with the social media platform you choose to share to.
