There are 3 options to access JARO, each of which directs you to another website:
1. Go to the publisher's journal site at Springer
2. If you are an ARO member and are logged in as such to this website, when you click the Springer JARO link, it should recognize you as a member and allow you full access. If this is not working for you, please inform firstname.lastname@example.org.
3. Go to the JARO Editor's website for additional information, paper highlights and other information - http://jaro-online.org/index.html.
