Membership History is the most frequently viewed in the Entitlement History. Its chart groups past memberships by type, and then by date within type, with the most recent at the top. The fields displayed are Type, Description, Start, Expire and Due.
Note that in the description field provides info in red when there were gaps between the expiration date of a membership and the start date of the next one, as to how long the membership was lapsed.
For an additional entitlement to appear on this screen, it must be something that someone has paid for and that has multiple classifications. Common examples include special interest groups, divisions, networks and subscriptions.
