Joining gtsystem is easy, and is open to any library, anywhere! If your library is part of a library system, it's usually the library system that should sign up and then individual library locations are created inside your library system's gtsystem site.
There's only two decisions you need to make to become a gtsystem partner and get your own gtsystem.org site. You need to tell us what you'd like your unique gtsystem site code should be, and tell us to whose email address we should send details for the admin account.
Send us an email at gtsystem at aadl.org with those details or any questions, and we'll get you set up and online!
