CD ROM subscription orders will be issued quarterly for all journals. The first CD ROM disc will be issued in April. Since CD ROM discs are cumulative, previously produced discs will not be provided. Online subscribers are required to have a valid e-mail address. There are no agency or library discounts given on subscriptions.
Domestic rates apply only to the U.S. and possessions.
Foreign rates apply to all other countries. For journals being shipped to foreign destinations, air delivery service is included in the price. Requests for cancellation made after an order has been processed and service has begun are subject to a service charge. A credit or refund will be given on the unserved portion of the subscription. Change of address requests are expedited if you include the current mailing label with notification of your new address.
