The price, therefore, is only an estimate of the annual cost for each subscription. Most NTIS subscriptions are issued annually. Once your subscription has expired, it will not automatically be renewed. However, we will notify you before the expiration date of your subscription and remind you to renew. Ongoing Subscriptions NTIS classifies some subscriptions as ongoing.
Ongoing subscriptions have no expiration date.
They continue until you write, e-mail, or fax us to stop your subscription. Upon the start of an ongoing subscription, you will be sent the next available issue. Your credit card or NTIS Deposit Account will incur charges whenever an issue is shipped. Customers forget that once an ongoing subscription is placed, issues continue to be sent until a written or faxed request for cancellation is received. Please include your name, address, telephone, and subscription title in the message.
