Payment First-time advertisers or agencies are required to pay at the time of the initial order. Other accounts are payable within 30 days of the invoice. Non-U.S. advertisers are required to pay in U.S. currency at the time of the initial order. Advertisers and agencies share dual liability for payment. Contrary agreements between advertisers and agencies, even if listed on insertion orders, are superseded by this condition of the American Library Association.
All advertising is subject to the publisher's approval.
The publisher reserves the right to reject advertising. Cancellations are not accepted after the closing dates for space reservations. Covers and special positions are non-cancellable.
