How often are the Learning Resources offered in the UBP revised?
Authors and/or providers are conscientious to keep their Learning Resources up to date. Providers will be notified if their Learning Resources have not been revised for a relatively long period of time. Nonetheless, as a consumer, you can specify that you want to be notified when Learning Resources of your interest get changed (see “Notification Preferences” in the submenu “Edit User Preferences” under the menu “Members & Registration”).
